· JVASP-93500· Ta2CN3

Ta2CN3 is a tantalum carbonitride ceramic compound that combines tantalum, carbon, and nitrogen to form a refractory ceramic material. This compound belongs to the family of transition metal carbonitrides, which are known for exceptional hardness and thermal stability at high temperatures. Ta2CN3 remains largely a research and development material rather than a mature commercial product, with potential applications in extreme-environment engineering where conventional ceramics or metals would fail.

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.
