Nano Hafnium Hf Powder CAS 7440-58-6

About Nano Hafnium Hf Powder:
Hafnium is a shiny, silvery, malleable metal. It is resistant to corrosion because it forms a tough, impenetrable oxide film on its surface. The metal is not affected by bases and acids, except hydrofluoric acids. Hafnium is difficult to separate from its fourth group partner zirconium because the two elements have the same atomic size. Hafnium powder is a light gray dry metallic powder. The dry powder reacts with water to produce hydrogen, a flammable gas. The reaction may produce enough heat to ignite hydrogen.
 
Found in all zirconium-bearing minerals, hafnium is a ductile metal with a bright silvery luster. It is powerful and extremely resistant to corrosion. Zirconium and hafnium have almost identical chemical properties (except that hafnium is twice as dense as zirconium), making it difficult to separate. The properties of hafnium are significantly affected by zirconium impurities. Tungstenmolybdenummetals is a trusted global Nano Hafnium Hf Powder supplier. Feel free to send an inquiry about the latest price of Hafnium at any time.

About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Tungstenmolybdenummetals provides a wide range of products for hydrogen storage research, advanced fuel cells, and battery applications. Hydrogen is easily produced from renewable energy sources and is the most abundant element in the universe. Hydrogen comes from many sources, such as solid fuels, water, and renewable materials. Hydrogen is non-polluting and will form harmless water during use. Challenges related to the use of hydrogen as an energy source include the development of safe, compact, reliable, and cost-effective hydrogen storage and transmission technology. Currently, hydrogen can be stored in three forms: compressed hydrogen, liquid hydrogen, and chemical storage. High purity, submicron and Nanopowder forms can be considered. Calcium nitride is the main raw material for high-end phosphors. This phosphor is more stable, has better performance, and has better effects at high temperature and high humidity.

Nickel Boride Ni2B Powder CAS 12619-90-8

CAS No. : 12619-90-8
EINECS No.: 235-723-2
Appearance: powder
Molecular Formula: Ni2B
Molecular Weight: 128.2

About Nickel Boride Ni2B Powder:
Nickel Boride is a chemical compound of nickel and boron with the formula Ni2B. It is one of the borides of nickel. The formula “Ni2B” and the name “nickel boride” are often used for a nickel-boron catalyst obtained by reacting nickel salts with sodium borohydride. 
Nickel boride catalyst can reduce unsaturated ethers, alcohols, aldehydes, esters, amines and amides to their corresponding saturated compounds without hydrogenation reaction. Unsaturated nitriles can be reduced to primary amines, while epoxides remain unchanged. In addition to sodium borohydride, dimethoxyborane (Meo)2BH4 or lithium borohydride LiBH4 can react with nickel chloride to obtain nickel boride catalysts for such reactions. It is worth emphasizing that only NiCl2 showed catalytic activity in the combined catalytic reduction of 2-methyl quinoline by a variety of transition metal salts, such as CoCl2, NiCl2, CuCl2, CrCl3 and sodium borohydride. Feel free to send an inquiry to get the latest price if you would like to buy Nickel Boride Ni2B Powder in bulk.

How is Nickel Boride Ni2B Powder produced?
Nickel Boride Ni2B can be obtained (together with other nickel borides) by heating sodium borohydride with powdered nickel-metal up to 670 °C in a closed vessel so that the released hydrogen creates a pressure of up to 3.4 MPa. The main reactions can be summarized as
2NaBH4 ↔ 2NaH + B2H6
2Ni + 2B2H6 + NaH ↔ Ni2B + 3BH3 + 2H2 + Na
but other reactions occur, yielding other borides.

Application of Nickel Boride Ni2B Powder:
Nickel boride catalyst is prepared by the reaction of nickel chloride NiCl2 with boron hydrogen reagents such as sodium borohydride NaBH4. It can be used for selective hydrogenation reaction, desulfurization reaction, dehalogenation reaction, hydrolysis reaction, and reduction of nitro and other functional groups.
The nickel boride catalyst prepared by the reaction of NiCl2 and NaBH4 can also be used for desulfurization reaction. Compared with the Raney nickel catalyst used in the traditional desulfurization reaction, it can obtain a higher yield, and at the same time, it can avoid the disadvantages of Raney nickel such as strong alkalinity, flammability and sensitivity to air and moisture.
In addition, thioamides, sulfides and sulfides can all be desulfurized under the catalysis of nickel boride to obtain corresponding hydrocarbons
Primary, secondary, and tertiary aliphatic nitro compounds can be reduced to amines in the presence of nickel boride.
The NiCl2/NaBH4 combination also achieves dehalogenation and hydrolysis reactions, reducing many α-bromoketones to ketones, or dibromo ketones to olefines, and reducing benzyl, allyl, and propargyl esters to the corresponding alkanes.

 

Storage Condition of Nickel Boride Ni2B Powder:
The damp reunion will affect Ni2B powder dispersion performance and using effects, therefore, nickel boride Ni2B powder should be sealed in vacuum packing and stored in cool and dry room, the nickel boride Ni2B powder can not be exposure to air. In addition, the Ni2B powder should be avoided under stress.

Packing & Shipping of Nickel Boride Ni2B Powder:
We have many different kinds of packing which depend on the nickel boride Ni2B powder quantity.

About Colloidal Silver Nano Silver Solution:
Nano Silver solution is a metallic Silver elemental with a particle size of 1-100nm. The particle size of the nanosilver is mostly about 20 nanometers, and a few can reach less than 5 nanometers. With a broad spectrum of bactericidal effects, about 650 kinds of bacteria, and do not produce drug resistance. Animal experiments showed that even if the dosage of nano-silver antibacterial powder reached thousands of times aboutthe standard dosage, the tested animals had no toxic performance. At the same time, it can also promote the repair of damaged epithelial cells. It is worth mentioning that the antibacterial effect of this product is increasingly enhanced when it meets water, which is more conducive to the treatment of diseases.
Nano-silver acting on cell membrane proteins can directly destroy bacterial cell membrane and oxygen metabolism enzyme (-SH), block bacteria and other microorganisms from the absorption of amino acids, uracil and other essential nutrients for growth, thus inhibiting their growth. This unique mechanism can kill most bacteria, fungi and other microorganisms. Nano-silver particles have super permeability and can quickly penetrate into the subcutaneous 2mm to sterilize, which has a good bactericidal effect on the deep tissue infection caused by common bacteria, stubborn bacteria, drug-resistant bacteria and fungi. Tungstenmolybdenummetals is a trusted global Colloidal Silver Nano Sliver Solution supplier.

About Tantalum Boride TaB2 Powder : Tantalum diboride is a gray powder. Tantalum diboride is completely insoluble in acid, nitric acid and aqua regia. Slightly soluble in hot sulfuric acid and hydrofluoric acid, soluble in molten alkali and sodium carbonate. The Vickers hardness of the TaB2 film and crystal is about 30 GPa.These materials are stable to oxidation and acid corrosion up to 700°C. TaB2 has the same hexagonal structure as most diborides (Alb 2, MGB2, etc.).It also has the following space groups: TAB (orthogonal-crystal system, iodized ((I), Cmcm), TA5B6 (Cmmm), TA3B4 (IMmm), TAB2 (hexagonal, aluminum diboride) type, P6 / mm2). Feel free to send an inquiry to get the latest price if you would like to buy Tantalum Boride TaB2 Powder in bulk.
