TiH3

Titanium hydride (TiH3) is an interstitial metal hydride compound formed when hydrogen dissolves into or reacts with titanium, functioning as a precursor material and hydrogen storage medium rather than a finished engineering material. It is primarily encountered in powder metallurgy processes—particularly in metal injection molding and powder production—where it serves as a controlled hydrogen source for reducing impurities or as a foaming agent in lightweight applications, and in hydrogen storage research where it represents an experimental approach to safe hydrogen containment. Engineers select TiH3 for specialized manufacturing steps where precise hydrogen introduction or temporary volumetric expansion is required, though it requires careful thermal management since decomposition releases hydrogen gas; this makes it most relevant in advanced fabrication rather than structural applications.
