Molybdenum Disulfide MoS2 Powder CAS 1317-33-5

About Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide (MoS2) is the main component of molybdenite. Black solid powder with a metallic luster. Chemical formula MoS2, melting point 1185°C, density 4.80g/cm3 (14°C), Mohs hardness 1.01.5. It starts to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C. It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide:
2MoS2+ 7 O2→ 2 MoO3 + 4 SO2 can be used to test the generated molybdenum trioxide with ferrotitanium reagent. First, the product is treated with sodium hydroxide or potassium hydroxide solution (the principle is to convert molybdenum trioxide into molybdate), and then the titanium iron reagent solution is added dropwise, which will react with the generated sodium molybdate or potassium molybdate to produce gold Yellow solution. This method is very sensitive, and trace amounts of molybdate can be detected. And if there is no molybdenum trioxide generated, the solution will not produce golden yellow, because molybdenum disulfide does not react with sodium hydroxide or potassium hydroxide solution.
Molybdenum disulfide can react with chlorine when heated to produce molybdenum pentachloride:
2 MoS2+ 7 Cl2→ 2 MoCl5+ 2 S2Cl2
Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2.
Molybdenum disulfide has a high content of active sulfur, which is easy to cause corrosion to copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but also to add copper corrosion inhibitors. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Disulfide MoS2 Powder in bulk.

How is Molybdenum Disulfide MoS2 Powder produced?
Natural law
MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter in the molybdenite concentrate, SiO2, Fe, Cu, by subjecting high-quality molybdenum concentrate to certain physical and chemical actions. Ca, Pb and other impurities are further refined to obtain nano-MoS2. However, the purity of the nano-MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is lower than 400℃, it is recommended to use the most expensive MoS2 when working in ordinary atmosphere. It has lubricating ability below 1300℃, and it is recommended to use the cost-based MoS2.
Chemical synthesis
The synthetic method can produce sulfides with high purity, less impurities, and fine particle size, and can prepare sulfides that meet different functional requirements. Therefore, the production of nano sulfides by synthetic methods has always attracted much attention. There are many methods for preparing nano-MoS2, such as ammonium tetrathiomolybdate thermal decomposition method, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotube space confinement method, hydrothermal synthesis method, high-energy physical method and chemical method combination and many more.

Applications of Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is diamagnetic, can convert linear photoconductors and semiconductors with P-type or N-type conductivity, and has the functions of rectification and energy conversion.
Molybdenum disulfide can also be synthesized as a catalyst for hydrocarbon dehydrogenation.
Molybdenum disulfide is also known as “the king of advanced solid lubricants”.
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate chemically purified by changing the molecular structure.
Molybdenum disulfide has good dispersibility and does not need to be added. It can be added to various greases to form a colloidal state and will never replace it, thereby increasing the lubricity and extreme pressure of the grease.
Molybdenum disulfide is also suitable for high temperature, high pressure, high viscosity and high load mechanical working conditions to extend the service life of the equipment.
The main function of molybdenum disulfide as a friction material is to reduce friction at low temperatures, increase friction at high temperatures, and reduce combustion loss. Easily volatilize in the friction material.
Anti-friction: The size of disulfide particles formed by supersonic jet pulverization can reach 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can be used in friction materials to take advantage of the anti-friction effect;
Increased friction: Molybdenum disulfide is not conductive, and silicon carbide, molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide are present. When the temperature of the friction material rises sharply due to friction, the shrinking molybdenum trioxide particles gradually heat up and expand, thereby increasing the friction in the axial direction.
Antioxidant: Molybdenum disulfide is obtained through a comprehensive chemical purification reaction, and its pH value changes 7-8, slightly alkaline. It covers the surface of the friction material, which can protect other materials from oxidation, especially making it difficult for other materials to move and enhancing adhesion.

Storage Condition of Molybdenum Disulfide MoS2 Powder:
Damp reunion will affect MoS2 powder dispersion performance and using effects, therefore, Molybdenum Disulfide MoS2 Powder powder should be sealed in vacuum packing and stored in cool and dry room, the Molybdenum Disulfide MoS2 Powder can not be exposure to air.

Copper Sulfide CuS Powder CAS 1317-40-4

Product Name: CuS Powder Copper Sulfide Powder CAS 1317-40-4
Purity: min 99%
Copper sulfide is an inorganic compound with a chemical formula of CuS or CuI2CuII(S2)S. Therefore, two-thirds of the sulphur is actually a persulfate ion, and two-thirds of the copper is a cuprous ion, which is dark brown and extremely polar. Insoluble, it is one of the most insoluble substances (second only to silver sulfide, mercury sulfide, and sulphide sulfide) because its poor solubility makes some seemingly unacceptable reactions.

About Copper Sulfide CuS Powder:
Copper sulfide is an inorganic compound with the chemical formula CuS, so it is actually a mixture of cuprous sulfide and supersulfide and is a black and brown amorphous powder or granular substance. It is extremely insoluble and is one of the most difficult substances to dissolve because its insolubility allows some seemingly impossible reactions to occur. Bonding in copper sulfide cannot be correctly described in terms of simple oxidation state forms because the properties of the Cu-S bond are somewhat covalent rather than ionic and have a high degree of delocalization, resulting in a complex electronic band structure.
Copper sulfide is a compound and mineral, which can be divided into three categories: single sulfide, disulfide and mixed single sulfide. Copper sulfide is naturally occurring in nature as a mineral, called cuprizone. It conducts electricity moderately. Both synthetic materials and minerals contain copper sulfide.
Copper sulfide describes a series of compounds and minerals from which minerals and synthetic materials are composed. Some copper sulfides are economically important ores. The main copper sulfide minerals include Cu2S(chalcocite) and CuS(copper porphyry).In the mining industry, bornite or chalcopyrite consisting of a mixed copper-iron sulfide is often referred to as “copper sulfide”.In chemistry, “binary copper sulfide” is any binary compound of the elements copper and sulfur. Regardless of their origin, the composition of copper sulfides varies greatly at 0.5 Cu/S 2 and includes many non-stoichiometric compounds. Feel free to send an inquiry to get the latest price if you would like to buy Copper Sulfide CuS Powder in bulk.

How is Copper Sulfide CuS Powder produced?
No sulfur and copper directly mixed heating to prepare copper sulfide, because the oxidation of sulfur is weak, the reaction will generate a mixture of copper sulfide and cuprous sulfide:
2Cu+S==△==Cu2S  ,   Cu+S==△==CuS
Can make copper powder and sulfur dissolved in carbon disulfide reaction at 100℃ to produce pure copper sulfide:
Cu+S==100℃ ,  CS2==CuS
Laboratory preparation of copper sulfide is usually prepared by adding H2S gas or soluble sulfide (such as sodium sulfide) into copper salt (mainly copper chloride and copper sulfate) solution through double decomposition reaction:
CuCl2+H2S====CuS↓+2HCl (weak acid to strong acid)
This reaction can occur because copper sulfide is too insoluble, causing the equilibrium to shift to the right.
CuSO4+Na2S====CuS↓+Na2SO4
 
Applications of Bismuth Oxide Bi2O3 powder:
Copper sulfide has the following uses:
Solar cell
Superionic conductor
photodetector
Conductive electrode
Photothermal spectral analysis conversion equipment
Microwave shielding coating
An active absorber of radio waves
Gas sensor
Infrared radiation polarizer

Storage Condition of Copper Sulfide CuS Powder:
The damp reunion will affect CuS powder dispersion performance and using effects, therefore, Copper Sulfide CuS Powder should be sealed in vacuum packing and stored in a cool and dry room, the Copper Sulfide CuS Powder can not be exposure to air.

Cadmium Sulfide CdS Powder CAS 1306-23-6

About Cadmium Sulfide CdS Powder :
Cadmium sulfide is an inorganic substance with a chemical formula of CdS. There are two crystals, the α-form is a lemon yellow powder, and the β-form is an orange-red powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. Cadmium sulfide is a yellow solid. It has two different crystal structures in nature, namely, the rare minerals clinopyroxene and leucite, but it is more commonly used as an impurity substituent in zinc ore with similar structure, sphalerite and wurtzite, while zinc ore Sphalerite and wurtzite are the main economic sources of cadmium. As a compound that is easy to separate and purify, it is the main source of cadmium in all commercial applications. Its bright yellow color made it used as a pigment for the yellow paint “Cadmium Yellow” in the 18th century.
 
Like zinc sulfide, cadmium sulfide has two crystal forms. More stable hexagonal wurtzite structure (present in Greenockite mineral) and cubic zinc mixed structure (present in Hawleyite mineral). In both forms, cadmium and sulfur atoms have four coordinates. There is also a high-pressure form with a NaCl rock salt structure.
 
Cadmium sulfide is a direct bandgap semiconductor (energy gap 2.42 eV). The proximity of its bandgap to the wavelength of visible light gives it a colorful appearance.
Both polymorphs are piezoelectric, and the hexagon is also pyroelectric.
CdS crystal can be used as the gain medium of solid-state lasers.
CdS can be used in combination with other layers in the form of thin films for certain types of solar cells. CdS is also one of the first semiconductor materials used in thin-film transistors (TFT).
 
The CdS film can be a piezoelectric film and has been used as a transducer that can operate at frequencies in the GHz range. Feel free to send an inquiry to get the latest price if you would like to buy Cadmium Sulfide CdS Powder in bulk.

How is Cadmium Sulfide CdS Powder produced?
Cadmium sulfide can be prepared by precipitation from soluble cadmium(II) salts with sulfide ions. This reaction has been used for gravimetric analysis and qualitative inorganic analysis.
 
Industrial cadmium ore is leached into cadmium sulfate with sulfuric acid, adjusted to pH=3.5 and precipitated with sodium sulfide, and the pH should not be too low.
 
The production of pigments usually involves precipitation of CdS, washing of solid precipitates to remove soluble cadmium salts, then calcination (roasting) to convert them into hexagons, and then grinding to produce powders. When cadmium sulfide selenide is required, CdSe and CdS will co-precipitate, and cadmium selenide will be generated during the calcination step.
 
Applications of Cadmium Sulfide CdS Powder :
Cadmium sulfide is called cadmium yellow and is used to color enamel, glass, ceramics, plastics and paint.
Nickel yellow is suitable for coloring almost all resins and is translucent in plastics. There is a light-colored cadmium yellow containing zinc sulfide in polyethylene, and the molding processing time should be extended appropriately because zinc sulfide will promote the decomposition of polyethylene plastic and make it green. Cadmium yellow should not be mixed with pigments containing copper or copper salts to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow and blue pigments can be mixed together to obtain green.
Cadmium sulfide is mainly used as a pigment owing to its good thermal stability, light and weather fastness, chemical resistance, and high opacity.
Other applications of cadmium sulfide are listed below:
Photoresistors
Thin-film transistors
Transducers
Solar cells
Electrochemical deposition
Sol-gel techniques
Screen printing.

How is Titanium Sulfide TiS2 Powder produced?
Titanium disulfide is prepared by the reaction of the elements around 500 °C.
Ti + 2 S → TiS2
It can be more easily synthesized from titanium tetrachloride, but this product is typically less pure than that obtained from the elements.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 films by chemical vapor deposition. Thiols and organic disulfides can be employed in place of hydrogen sulfide.
A variety of other titanium sulfides are known.
 
Applications of Titanium Sulfide TiS2 Powder:
The prospect of titanium disulfide as a cathode material for rechargeable batteries was proposed in 1973. Groups IV and V halogen compounds have attracted attention for their high electrical conductivity. The original described battery used a lithium anode and a titanium disulfide cathode. The energy density of the battery is high, the diffusion process of lithium ions to titanium disulfide cathode is reversible, and the battery can be charged.
Titanium disulfide was chosen because it is the lightest and cheapest chalcogenide.
Lithium-ion diffuses fastest in titanium disulfide.
The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to charge. In addition, titanium disulfide is the lightest and cheapest of all the IV and V groups of layered dihalides.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
The use of TiS2 cathodes in solid-state lithium batteries most lithium-ion batteries use liquid electrolytes, which can pose safety concerns due to their flammability. A number of different solid electrolytes have been proposed to replace these hazardous liquid electrolytes.
For most solid-state batteries, high inter interface resistance reduces the reversibility of the intercalation process and shortens the service life. For TIS2, these undesirable interface effects are less of a problem. The power density of the all-solid-state lithium battery is 1000 W/kg and the maximum power density is 1500 W/kg in 50 cycles. In addition, the battery’s average capacity dropped by less than 10% in 50 cycles. Although titanium disulfide has high conductivity, high energy density and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathode.

Storage Condition of Titanium Sulfide TiS2 Powder:
The damp reunion will affect TiS2 powder dispersion performance and using effects, therefore, Titanium Sulfide TiS2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Titanium Sulfide TiS2 Powder can not be exposure to air. In addition, the TiS2 powder should be avoided under stress.
