'''Zirconium(II) hydride''' ([[Zirconium|Zr]][[Hydrogen|H<sub>2</sub>]]) 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 foam]]s. It is also used as a [[neutron moderator]] in [[neutron temperature|thermal-spectrum]] [[nuclear reactor]]s such as the [[TRIGA]] research reactor developed by [[General Atomics]]. Other uses include acting as a fuel in [[pyrotechnic composition]]s, namely [[pyrotechnic initiator]]s.
