· JVASP-147539· Ta5Si3N

Ta5Si3N is a tantalum silicide nitride ceramic compound combining refractory metal (tantalum) and ceramic (silicon nitride) phases to create a material with potential for ultra-high-temperature applications. This is a research-stage material primarily studied for aerospace and extreme-environment uses where exceptional thermal stability, oxidation resistance, and hardness are required beyond the capabilities of conventional ceramics or superalloys.

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.
