Zirconium Hydride (ZrH2) Micron Powder
Zirconium hydride describes an alloy made by combining zirconium and hydrogen with the symbol ZrH2. Its melting point is approximately 800℃ and has a density of 5.8 g/cm3. Zirconium hydride with increased hydrogen content can be made harder and stronger than zirconium, but such zirconium hydride is also less ductile than zirconium. Zirconium hydride powders are soluble in hydrofluoric acid or alcohol; they react violently with water, acids, oxidizers or halogenated compounds. Zirconium hydride powders are odorless, dark gray to black metallic powders. Zirconium hydride micron powder is used as strong reducing agents, and foaming agents. It is also used as additive in hard alloys. It is also used as a neutron moderator in thermal-spectrum nuclear reactors. Moreover, ZrH2 is used in powder metallurgy, as a hydrogenation catalyst, and as a reducing agent, vacuum tube getter, and a foaming agent in production of metal foams. Other uses include acting as a fuel in pyrotechnic compositions, namely pyrotechnic initiators.
