· Ti4 Si4 Rh4

Ti₄Si₄Rh₄ is an intermetallic compound combining titanium, silicon, and rhodium in a 1:1:1 molar ratio. This is a research-phase material within the titanium-based intermetallic family, where the addition of rhodium (a refractory noble metal) to titanium silicides is designed to enhance high-temperature stability, oxidation resistance, and potentially improve fracture toughness compared to conventional Ti–Si compounds. Applications remain primarily in academic and aerospace R&D contexts rather than established production use, targeting ultra-high-temperature structural applications where cost and processing complexity are secondary to thermal performance.

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.
