· JVASP-125448· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
