· TiS

Titanium sulfide (TiS) is an intermetallic compound combining titanium with sulfur, belonging to the transition metal chalcogenide family. While not a mainstream structural material, TiS and related titanium sulfides appear primarily in research contexts for solid-state chemistry, catalysis, and energy storage applications where their unique electronic and chemical properties offer advantages over conventional metals or ceramics. Engineers may encounter TiS in advanced research programs focused on hydrogen evolution catalysts, thermal energy storage systems, or specialized high-temperature coatings, though commercial deployment remains limited compared to titanium alloys or pure titanium.
