· JVASP-107756· Hf2CN

Hf2CN is a hafnium carbonitride ceramic compound belonging to the MAX phase or transition metal carbide/nitride family, materials known for combining ceramic hardness with metallic toughness and thermal stability. This material is primarily investigated in research and emerging applications for ultra-high-temperature structural applications, thermal protection systems, and wear-resistant coatings, where its hafnium base provides exceptional oxidation resistance and refractory properties that exceed conventional carbides.

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.
