CrHfON2
ceramic· CrHfON2
CrHfON2 is an advanced ceramic compound combining chromium, hafnium, oxygen, and nitrogen—a complex oxinitride belonging to the high-entropy or multi-principal-element ceramic family. This is a research-phase material designed to leverage the thermal stability of hafnium oxide and the hardness contributions of chromium nitride for extreme-environment applications. The material is notable for its potential to operate at very high temperatures while maintaining mechanical integrity, making it a candidate for next-generation thermal barrier coatings, cutting tools, and wear-resistant surfaces where conventional ceramics or single-phase nitrides reach performance limits.

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.
