· JVASP-108733· TaVCN

TaVCN is a refractory metal carbide-nitride composite belonging to the high-entropy ceramic family, combining tantalum, vanadium, carbon, and nitrogen in a single-phase structure. This material is primarily of research and developmental interest for extreme-environment applications where conventional superalloys reach their limits, offering potential benefits in thermal stability, hardness, and oxidation resistance. The material represents the emerging class of multi-principal-element ceramics designed to replace traditional binary or ternary carbides and nitrides in aerospace and power-generation contexts.

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.
