 Zirconium hydride (CAS NO.7704-99-6) 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 or the Soviet TOPAZ nuclear reactors. Other uses include acting as a fuel in pyrotechnic compositions, namely pyrotechnic initiators.

Reported in EPA TSCA Inventory.
