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. ==See also== *[[Tannerite]] ==References== {{Unreferenced|date =September 2007}} <references/> [[Category:Metal hydrides]] [[Category:Zirconium compounds]] [[Category:Nuclear materials]] [[Category:Pyrotechnic fuels]] {{inorganic-compound-stub}} [[ar:هيدريد زركونيوم ثنائي]]
