· ReHfO2N

ReHfO2N is an experimental ceramic compound combining rhenium, hafnium, oxygen, and nitrogen—a refractory oxynitride material designed for extreme-temperature applications. This material belongs to the family of high-entropy and ultra-high-temperature ceramics (UHTCs), which are of significant research interest for aerospace and energy applications where conventional ceramics fail. ReHfO2N and related oxynitride systems are being investigated as potential alternatives to traditional oxides for environments exceeding 1500°C, offering the possibility of improved oxidation resistance and mechanical stability at temperature through nitrogen incorporation.

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.
