Aluminum Oxide Al2O3 CAS 1344-28-1

About Aluminium oxide:
Aluminum oxide is an electrical insulator, it has a fairly high thermal conductivity to ceramic materials. The most common form of crystalline alumina is called corundum. Alumina can provide activated, super-activated, acidic, alkaline and neutral grades, and has flash grades, TLC, biomass purification, decolorization, dioxin analysis, PCB removal, pyrogen removal and biotechnology wide-pore forms. Oxide does not conduct electricity. However, certain oxides of perovskite structures have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, so they can be used in ceramic structures, such as clay bowls for the production of advanced electronic devices, and lightweight structural components used in aerospace and electrochemical applications, such as fuel cells. Exhibits ionic conductivity. Metal oxides are basic acid anhydrides, so they can react with acids and strong reducing agents in redox reactions. Reactive chromatography grade alumina is used in lighting, photographic chromatography and various chromatographic separation techniques. Alumina is usually available in most quantities immediately. High purity, sub-micron and nanopowder forms can be considered. Alumina can also be made into particles, pellets, powders, sputtering targets, tablets and nano-powders.

How is Aluminium oxide produced?
Aluminum oxide is produced by the bauxite process. The Bayer process is carried out in four steps. First, the bauxite is crushed, washed and dried, and then dissolved with caustic soda at high temperatures. Next, the mixture is filtered to remove impurities called “red mud” and discarded appropriately. The remaining alumina solution is transferred to a high tank called a settler. In the sedimentation tank, the hot solution begins to cool, and aluminum hydroxide seeds (very small particles) are added. The aluminum hydroxide seeds stimulate the precipitation of solid aluminum hydroxide crystals. Aluminum hydroxide precipitates at the bottom of the tank and is removed. Finally, all remaining caustic soda in the aluminum hydroxide is washed and heated to remove excess water. After this process, alumina (alumina) appears as a fine white powder. It looks a lot like sugar used in baking, but it is hard enough to scratch the glass plate.
 
Application of Aluminium oxide:
Most of the alumina produced is used to form aluminum metal. Oxygen usually reacts with metallic aluminum to catalyze corrosion. However, when combined with oxygen to form alumina, it forms a protective coating and prevents further oxidation. This increases the strength and makes the material less prone to deterioration. Alumina is mainly used as analytical reagents, dehydration of organic solvents, adsorbents, organic reaction catalysts, abrasives, polishing agents, raw materials for smelting aluminum, and refractory materials.
Industries that use alumina include:
Medical industry
Due to the hardness, biological inertness and chemical properties of alumina, it is used for hip replacement surgery prostheses, bionic implants, artificial eye substitutes, tissue reinforcement materials, crowns, abutments, bridges and other dental implants. The preferred material of the bearing. It is also used in laboratory equipment and tools such as crucibles, furnaces and other laboratory appliances.
Military and protective equipment
The strength and lightweight properties of alumina help to strengthen body armor, such as breastplates and armor for cars and airplanes, which is its largest market. Alumina is also used to synthesize sapphire bulletproof windows and bulletproof systems.
Electrical and electronic industry
Its high melting point and high boiling point, as well as its excellent heat resistance, make alumina an ideal material for high-temperature furnace insulators and electrical insulators.

Antimony Tin Oxide ATO Powder CAS 128221-48-7

About Antimony Tin Oxide ATO Powder:
Antimony tin oxide, also called antimony doped tin dioxide, antimony tin oxide, abbreviated as ATO. It is a non-resistive transparent conductive material in the semiconductor field. It can be used in various glass, plastics and various resins to play a role in transparency, conductivity, anti-static radiation, ultraviolet and infrared blocking. Tin oxide antimony conductive nanomaterials have broad application prospects in many fields due to their high conductivity and light color transparency. It is a new type of functional material that has developed rapidly in recent years.
 
Antimony tin oxide is a world-recognized excellent material with a series of unique properties. They show good electrical conductivity in antistatic applications and have good infrared absorption capabilities. Strong absorption of near-infrared light occurs, and transparency in the visible light range can be maintained in the film.
 
ATO (Antimony Tin Oxide) is a highly insoluble, thermally stable source of aluminum suitable for glass, optical and ceramic applications. Antimony tin oxide is one of the most commonly used transparent conductive oxides because it has two key properties, including optical transparency and conductivity. These characteristics are very important for photovoltaic devices including solar cells and flat-panel displays.
 
The current technology for forming particulate and nanoparticulate tin oxide and using an acidic medium to provide a surface coating, however, coating acid-sensitive materials with nanoparticulate antimony-doped tin oxide (ATO) films has become very important.
 
The antistatic coating is the main application market of nano ATO powder. Nano-composite transparent antistatic coatings can be prepared by adding nano-ATO powder as a conductive filler to the matrix resin (such as polyamide and acrylic) and selecting an appropriate dispersion method. Since the previous conductive fillers usually use carbon black, they are inferior to ATO powder in terms of color control.

Copper oxide is mainly used for making rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizes, insecticides, hydrogen production, catalysts, green glass, etc.

Technical Parameter of Copper Oxide CuO Powder:

 How is Cuprous Oxide CuO powder produced? 
There are several methods of industrial production of copper oxide
1. Copper powder oxidation method
Using copper ash and copper slag as raw materials, it is roasted and heated with coal gas for preliminary oxidation to remove moisture and organic impurities in the raw materials. The generated primary oxide is naturally cooled, and after pulverization, it undergoes secondary oxidation to obtain crude copper oxide. The crude copper oxide is added to a reactor pre-installed with 1:1 sulfuric acid, and the liquid is reacted with heating and stirring until the relative density of the liquid is doubled, and the pH value is 2 to 3 as the end of the reaction, and a copper sulfate solution is generated. After clarification, under heating and stirring conditions, iron shavings are added to replace copper and then washed with hot water until there is no sulfate and iron. After centrifugal separation, drying, oxidation roasting at 450°C for 8 hours, cooling, crushing to 100 meshes, and then oxidation in an oxidation furnace to obtain copper oxide powder.
2. Nitration of copper wire or copper powder
Dissolve the copper wire or copper powder in 6mol/L nitric acid to keep the copper in excess, heat the solution to a pH value of 3-4 to remove the iron hydroxide precipitate, then mix it with 10% (mass) sodium carbonate solution and heat to boiling. Alkaline salt is precipitated, discard the supernatant, wash thoroughly with water, filter and dry. The dried basic copper carbonate is heated and decomposed into black copper oxide powder under a small fire with sufficient stirring: CuCO3·Cu(OH)2=2CuO+CO2↑+H2O
When no more carbon dioxide is produced, the decomposition is complete.
3. Copper nitrate thermal decomposition method
The electrolytic copper is dissolved in dilute nitric acid and evaporated to dryness on a water bath, and then heated in a desiccator from 90°C to 120°C very slowly. When the soft basic salt is formed, it is boiled in water, filtered and dried; then it is slowly heated to 400℃ to remove most of the nitric acid; then crushed and heated to 850℃ for 1h to decompose into oxidation copper. To make the reaction more complete, the product can be pulverized again, heated at about 700°C for 1 hour, and then placed in a desiccator to cool.
4. Conductive water dissolution method
Dissolve high-purity copper nitrate with conductive water, filter, add excess high-purity NH3·H2O to the clear liquid, filter out impurities and precipitate, and use high-purity nitric acid to neutralize the filtrate to precipitate copper hydroxide. Filter, wash once with conductive water, add nitric acid to dissolve the precipitate, add high-purity ammonium carbonate to precipitate copper carbonate, then wash, spin dry, dry in an oven at 200°C, burn at 450-550°C for 3 to 4 hours, and get Spectral pure copper oxide:
5. Copper carbonate thermal decomposition method
Put copper powder or copper wire in a fume hood with as little 6mol/L nitric acid as possible to completely dissolve it. If the solution is opaque, it needs to be filtered. Besides, the sodium carbonate solution is mixed with the copper nitrate solution and boiled to generate black basic salt precipitation. When the solid settles, discard the supernatant liquid, fully wash, filter, and dry by decantation. Put it on an evaporating dish and heat it with a small fire with sufficient stirring to decompose it into copper oxide.

Applications of Cuprous Oxide CuO powder:
As a significant product of copper mining, copper(II) oxide is the starting point for the production of other copper salts. For example, many wood preservatives are produced from copper oxide.
Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes.
It is also incorrectly used as a dietary supplement in animal feed. Due to low bioactivity, negligible copper is absorbed.

Indium Tin Oxide ITO Powder

About Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is a ternary composition of different ratios of indium, tin and oxygen. According to the oxygen content, it can be described as ceramic or alloy. Usually encountered indium tin oxide as an oxygen-saturated composition, its formulation is 74% In, 18% O2 and 8% Sn by weight. Oxygen-saturated compositions are so typical that unsaturated compositions are referred to as oxygen-deficient ITO. The thin layer is transparent and colorless, and the bulk is a pale yellow to gray. In the infrared region of the spectrum, it acts like a metal mirror.
 
Indium tin oxide is one of the most widely used transparent conductive oxides because of its electrical conductivity and optical transparency and the ease with which it is deposited as a thin film. As with all transparent conductive films, a compromise must be made between conductivity and transparency, because increasing the thickness and increasing the concentration of charge carriers will increase the conductivity of the film, but will reduce its transparency.
 
Indium tin oxide films are most commonly deposited on the surface by physical vapor deposition. Usually, electron beam evaporation or a series of sputtering deposition techniques are used.
 
ITO is a mixed oxide of indium and tin. Depending on the composition, its melting point is in the range of 1526-1926°C. The composition of the most commonly used material is ca In4Sn. This material is an n-type semiconductor with a large bandgap of about 4 eV. ITO is transparent to visible light and has relatively high electrical conductivity. These features have great advantages in touch screen applications such as mobile phones.

Therefore, indium tin oxide is usually sprayed on glass, plastic and electronic display screens, used as a transparent conductive film, while reducing harmful electronic radiation and ultraviolet and infrared.
In the oxide conductive film, the Sn-doped In2O3 (ITO) film has the highest transmittance and the best conductive performance, and it is easy to etch fine patterns in the acid solution, of which the light transmittance is more than 90%. The transmittance and resistance of ITO are controlled by the ratio of In2O3 and SnO2, usually SnO2:In2O3=1:9.

Technical Parameter of  Indium Tin Oxide ITO Powder:

How is Indium Tin Oxide ITO Powder produced?
The ITO powder usually adopts the following preparation method: respectively oxidizing metal indium and metal tin to obtain indium oxide powder and tin oxide powder and then mixing and dispersing the indium oxide powder and tin oxide powder. In this method, it is difficult to completely synchronize the control conditions such as metal indium and metal tin as the basic raw material, such as the dissolution rate, dissolution temperature, neutralization pH value, neutralization temperature, and stirring speed, so the prepared indium oxide powder, The particle size deviation of tin oxide powder is large, which affects the quality of ITO film. In order to solve the problem of the uniformity of ITO powder, the co-precipitation method is also used to produce ITO powder. This method uses nitric acid to dissolve metal indium and metal tin, and then mix the resulting indium nitrate and tin nitrate according to the ratio, and then use ammonia to co-precipitate. Precipitation to obtain co-precipitated hydroxide, and finally, calcination to obtain indium tin oxide.
 
Applications of Indium Tin Oxide ITO Powder:
Indium tin oxide (ITO) is an optoelectronic material that has been widely used in research and industry. ITO can be used in many applications, such as flat panel displays, smart windows, polymer-based electronics, thin-film photovoltaic products, glass doors for supermarket freezers and architectural windows. Also, the ITO film used for the glass substrate helps the glass window to save energy.
 
The ITO green belt is used to produce electroluminescent, fully functional and fully flexible lamps. Besides, the ITO film is mainly used as an anti-reflective coating and is used in liquid crystal displays (LCD) and electroluminescence, where the film is used as a conductive transparent electrode.
 
ITO is commonly used to make transparent conductive coatings for displays (such as liquid crystal displays, OLED displays, plasma displays, touch panels, and electronic ink applications). ITO film is also used for organic light-emitting diodes, solar cells, antistatic coatings and EMI shielding. In organic light-emitting diodes, ITO is used as the anode (hole injection layer).
 
The ITO film deposited on the windshield is used to defrost the windshield of the aircraft. Heat is generated by applying a voltage to the film.
 
ITO is also used in various optical coatings, the most famous being infrared reflective coatings (hot mirrors) used in automobiles and sodium vapor lamp glass. Other uses include gas sensors, anti-reflective coatings, electrowetting on dielectrics, and Bragg reflectors for VCSEL lasers. ITO is also used as an infrared reflector for low emissivity window panes. Starting with the Kodak DCS 520, later Kodak DCS cameras also used ITO as a sensor coating to enhance the response of the blue channel.
 
ITO thin film strain gauges can operate at temperatures up to 1400°C and can be used in harsh environments such as gas turbines, jet engines and rocket engines.

Green Nickel Oxide NiO CAS 1313-99-1

About Nickel Oxide NiO :
Nickel oxide is an inorganic substance with a chemical formula of NiO and a molecular weight of 74.71.
What is NiO in chemistry? 
Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel. Nickel(II) oxide is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. It is a green-black cubic crystal. It is soluble in acid and ammonia but insoluble in water. Is nickel oxide soluble? Nickel oxide is soluble in acids, potassium cyanide, and ammonium hydroxide. It is insoluble in both cold and hot water, and caustic solutions. The color turns yellow when heated. It is obtained by the action of nickel and oxygen at a temperature greater than 400°C, or by pyrolysis of nickel carbonate at 350°C. Used to make alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and catalysts. 

Main properties of Nickel oxide 

 
What is the charge of NiO? 
0 is the charge of NiO.
Nickel oxide is the main oxide of nickel. It is classified as an alkali metal oxide. Millions of kilograms of products with different qualities are produced every year, mainly as intermediates for nickel alloy production. The mineral form of NiO (arsenite) is very rare. The protection of other nickel(III) oxides, such as Ni2O3 and NiO2 is also claimed but has not been proven by X-ray crystallography.

Conceptually simple structures are often called rock salt structures. Like many other binary metal oxides, NiO is usually not stoichiometric, which means that the Ni:O ratio deviates from 1:1. In nickel oxide, this non-stoichiometric NiO is accompanied by a color change. The stoichiometric correct NiO is green, and the non-stoichiometric NiO is black.

Performance of Nickel Oxide NiO Powder :
Nickel oxide is obtained by the action of nickel and oxygen at greater than 400℃, or by pyrolysis of nickel carbonate at 350℃. Used for making alloys, batteries, glass, enamel, ceramics, electronic components, nickel salts, and as a catalyst.

How is Nickel Oxide NiO produced?
NiO can be prepared by various methods. When heated to above 400°C, nickel powder reacts with oxygen to form NiO. In some commercial processes, green nickel oxide is made by heating a mixture of nickel powder and water at 1000°C. The reaction rate can be increased by adding NiO.
The simplest and most successful preparation method is to pyrolyze nickel (II) compounds (such as hydroxides, nitrates and carbonates) to produce a light green powder. By heating the metal in oxygen, the synthesis of the elements can produce gray to black powder, which indicates that the stoichiometry is wrong. It combines with sodium and potassium oxides at high temperatures (> 700°C) to form corresponding nickelates.
In addition, nickel oxide nanoparticles can be produced by thermally decomposing newly prepared nickel hydroxide through a sol-gel route at 300°C (572°F). X-ray diffractometer and vibrating sample magnetometer can be used to characterize the nickel oxide nanoparticles produced by this method.

Technical Parameter of Nickel Oxide NiO Powder :

Application of Nickel Oxide NiO Powder :
NiO has a variety of professional applications. Usually, it is used to distinguish between “chemical grade” and “metallurgical grade”. “Chemical grade” is a relatively pure material used for special applications, while “metallurgical grade” is mainly used to produce alloys. Used in the ceramic industry to manufacture glass powder, ferrite, and enamel. The sintered oxide is used to produce nickel steel alloys. Charles Edouard Guillaume (CharlesÉdouard Guillaume) won the 1920 Nobel Prize in Physics for his research on nickel-steel alloys, which he called Invar and Invar. 
What is nickel oxide used for?
Nickel oxide has a range of applications such as: For making electrical ceramics such as thermistors and varistors e.g. ferrites (nickel-zinc ferrite) Pigments for ceramic, glasses, and glazes.
NiO is a commonly used hole transport material in thin-film solar cells. It is also a component of nickel-iron batteries (also known as Edison batteries) and a component of fuel cells. It is the precursor of many nickel salts, used as specialty chemicals and catalysts. Recently, until the development of environmentally friendly NiMH batteries, NiO was used to manufacture NiCd rechargeable batteries used in many electronic devices.
Is nickel oxide toxic? 
CLINICAL FEATURES: ACUTE EXPOSURE Although nickel oxide is a pulmonary irritant, acute exposure is unlikely to result in significant poisoning. Documented clinical cases invariably involve chronic occupational inhalation.
NiO is an anode electrochromic material and has been extensively studied as a counter electrode of tungsten oxide and cathode electrochromic material in complementary electrochromic devices.
NiO is used as a binder and colorant for enamel in the pusher industry.
The ceramic industry is used as a raw material for colorants.
Used as a raw material for nickel-zinc ferrite in the production of magnetic materials.
Colorant for stained glass and tubular glass bulbs in the glass industry.
It is also a material used to manufacture nickel salts, nickel catalysts and secondary batteries.
