Zirconium Hydride ZrH2 Powder CAS 7704-99-6

About Zirconium Hydride ZrH2 Powder:
The hydride zirconium chemical ZrH2, density is 5.6 g / cm3, and the melting is decomposed, and heat-39.7 kcal/mol is formed. Its preparation method is carried out with titanium hydrogenated, and the temperature of the hydrogenation is often carried out at 900 ° C. The molecular weight of zirconium hydride is 93.24. Zirconium hydrogen fluid can be dissolved in hydrofluoric acid or ethanol; they have severely reacted with water, acid, oxidant or halogenated compound.
Zirconium hydrogen fluid is a stable powder, and the air and water are stable under normal conditions. It can react violently with oxidizing agents and strong acids, zirconium can smoothly burn smoothly when ignition, and decompose in vacuum 300 ° C, completely decompose at 500-700 ° C.
L. zirconium hydride depicts an alloy bonded from zirconium and hydrogen. Hydrogen is used as a hardening agent to prevent dislocation in zirconia atomic lattices. By changing the content of hydrogen and hydrogen in the presence of hydride (precipitation phase), the hardness, ductility, and tensile strength of the resulting hydride can be controlled. The zirconium hydride having a hydrogen content can make it harder, stronger than zirconium, but the toughness of such zirconia is not as zirconium. Feel free to send an inquiry to get the latest price if you would like to buy Zirconium Hydride ZrH2 Powder in bulk.

Zirconium Hydride Powder CAS 7704-99-6:

It is a stable powder that is stable to air and water under normal conditions. It reacts violently with oxidants and strong acids. It burns smoothly during ignition, begins to decompose at 300 ° C in a vacuum, and completely decomposes at 500-700 ° C.

How is Zirconium Hydride ZrH2 Powder produced?
The metal is interacting with hydrogen to form zirconium hydrogenide. Sponge metallic zirconium with a purity of 99.8% was heated to high purity hydrogen (99.999%) to 400 to 600 ° C, directly reacted, ie, zirconium hydrogen fluid. The reaction is an exothermic reaction. This reaction also occurs even at room temperature, and uniform integral hydrogenation is usually achieved by annealing at a temperature of 400-600 ° C for several hours to several weeks. At room temperature, zirconium hydrogenide in the air, even in a high vacuum, will be rapidly oxidized. The formed nano-thin oxide layer prevents oxygen from further diffused into the material, so changes caused by oxidation can generally be ignored. Or reduce zirconium dioxide at 600 ° C in a hydrogen stream, and zirconium hydride can be obtained.
 
Applications of Zirconium Hydride ZrH2 Powder:
Zirconium hydride is a pure powder, used as a hydrogenation catalyst in powder metallurgy, used as an absorbent in the vacuum tube industry. In a vacuum system, zirconium hydride helps establish a seal between metals and ceramics.
Zirconium hydrogenide is used in industrial use for fireworks, flux and ingredients, used in a nuclear reactor as a chuck, in a vacuum tube, and is also used in metal-ceramic sealing.
ZrH2 is used in powder metallurgy, used as a hydrogenation catalyst, used in metal foam production as a reducing agent, vacuum tube, and foaming agent. Other uses include fuel as a firework, i.e., fireworks exploding.
Zirconium hydride is a strong reducing agent. Use it as an additive. Desoxicide and desulfurization agents at the time of iron alloy are prepared.
Mixed with carbonized calcium carbon carbide and nitride can be used as a metal coating.
Since the ceramics can be infiltrated, zirconium is used as a metal-ceramic adhesive for vacuum tubes and ceramic devices.
In addition, zirconium hydride can also be used as a neutron reduction agent and an atomic power station other material, a suction agent, a firework, ambient solvent or the like.

Storage Condition of Zirconium Hydride ZrH2 Powder:
The damp reunion will affect ZrH2 powder dispersion performance and using effects, therefore, Zirconium Hydride ZrH2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Zirconium Hydride ZrH2 Powder can not be exposure to air. In addition, the ZrH2 powder should be avoided under stress.
