Titanium hydride (TiH2) is a chemical compound of titanium and hydrogen, a hydride. It is highly reactive and needs to be kept away from heat and strong oxidizers.
Titanium hydride is together with potassium perchlorate used in some igniter pyrotechnic compositions and flash powders. It also can be used to create hydrogen and titanium hydroxide. It is created by the reaction of titanium and hydrogen.
Titanium hydride is used as foaming agent in production of metal foams.
