Titanium hydride

Titanium hydride normally refers to the inorganic compound TiH2 and related nonstoichiometric materials. It is commercially available as a stable grey/black powder, which is used as an additive in the production of Alnico sintered magnets, in the sintering of powdered metals, the production of metal foam, the production of powdered titanium metal and in pyrotechnics.

This article is about the stable titanium hydride. For the unstable molecular chemical compound, see Titanium(IV) hydride.

Also known as titanium–hydrogen alloy, is an alloy of titanium, hydrogen, and possibly other elements. When hydrogen is the primary alloying element, its content in the titanium hydride is between 0.02% and 4.0% by weight. Alloying elements intentionally added to modify the characteristics of titanium hydride include gallium, iron, vanadium, and aluminium.
