· SiTaN3

Silicon titanium nitride (SiTaN₃) is a ternary ceramic compound combining silicon, titanium, and nitrogen phases, typically synthesized as a composite or solid-solution material. This material family is primarily pursued in research and advanced development contexts for applications requiring extreme hardness, thermal stability, and wear resistance at elevated temperatures. Industrial adoption remains limited compared to established alternatives like TiN or Si₃N₄, but SiTaN₃ shows promise in niche wear-critical and high-temperature applications where conventional nitride coatings approach performance limits.

Regulatory Screening

Environmental

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.
