Zirconium Hydride Powder（ZrH2） 

Properties of zirconium hydride

English name: zirconium hydride/zirconium dihydride

EINECS 231-727-3

molecular weight ZrH2

molecular weight 93.24

zirconium hydride chemical ZrH2, density 5.6g/cm3, was prepared in the same 

manner as titanium hydride, hydrogenation temperature is usually 900 it is a 

stable powder stable to air and water under normal conditionsIt can violently 

with antioxidant and acid reaction, it can smoothly in ignition burning, in 300 

starts to break down in a vacuum, in 500-700 complete decomposition zirconium 

hydride appearance is metal, black powder generated heat 124 kj/mol, and 

electrical conductivity between metals and semiconductors, 10-3 when pressure 

is 1.33 pa in the 400 release of hydrogen for metal and weak acid to water, 

under normal circumstances is not reaction, soluble in 1% ~ 5% of hydrofluoric 

acid in it can react violently with oxidant and acid to be ignited, burning The 

purpose of zirconium hydride

Zirconium hydride is used for fireworks flux and ignition agent in the industry, 

used in nuclear reactors as the moderator, getter in the vacuum tube, also 

used in metal - ceramic seal hydrogenated titanium and zirconium hydride 

industry has a ton of generation and supply, but it is mainly used for military 

purposes zirconium hydride as a strong reductant used as additive in preparation 

of ferroalloy deoxidizer and desulphurizer is mixed with calcium carbide and 

nitride, can be used as a metal coating because can infiltrate ceramic, look 

for metal - ceramic binder, used for vacuum tube and ceramic componentsIn 

addition, it is used as neutron reductor and other materials of nuclear power 

station, getter for vacuum tube, fire trap and flux, etc. Its application examples 

are as follows:

1) Preparation of a kind of zirconium hydride surface hydrogen resistance coating.

2) preparation of a spray powder, including aluminum powder zirconium hydride 

powder and boron carbide powder. 

3) preparation of a touch screen silver paste.
