· Si4 Ti2

Si₄Ti₂ is a titanium-silicon ceramic compound belonging to the transition-metal silicide family, known for its high stiffness and thermal stability. This material is primarily investigated in research contexts for high-temperature structural applications, aerospace components, and wear-resistant coatings where conventional metals reach their limits. Its combination of ceramic hardness with metallic properties makes it attractive as an alternative to superalloys and refractory ceramics, though industrial adoption remains limited compared to established titanium alloys or monolithic ceramics.

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.
