Zirconium(II) hydride (ZrH2) is a chemical compound, a hydride of zirconium. The commercial form is usually a flammable, gray-black powder.
It 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. It is also used as a neutron moderator in thermal-spectrum nuclear reactors such as the TRIGA research reactor developed by General Atomics. Other uses include acting as a fuel in pyrotechnic compositions, namely pyrotechnic initiators.
