· Si4Ti5

Si4Ti5 is an intermetallic compound in the titanium-silicon system, representing a stoichiometric phase that combines the lightweight and high-temperature capabilities of titanium with silicon's refractory properties. This material family is primarily of research and development interest, as titanium silicides offer potential for high-temperature structural applications where conventional titanium alloys reach their limits, though processing and brittleness challenges have limited widespread industrial adoption compared to nickel-based superalloys.

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.
