· CrHfO2N

CrHfO2N is an advanced ceramic compound combining chromium, hafnium, oxygen, and nitrogen—a member of the oxynitride ceramic family designed for extreme-temperature and high-wear applications. This material is primarily research-focused, developed to combine the thermal stability of hafnium oxides with the hardness and oxidation resistance imparted by chromium and nitrogen phases. It represents an emerging class of multi-element ceramics engineered for environments where conventional oxides or nitrides alone fall short, such as aerospace propulsion systems, cutting tools, and protective coatings.

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.
