· OsHfOFN

OsHfOFN is an experimental refractory ceramic compound containing osmium, hafnium, oxygen, and nitrogen—a high-entropy or complex oxycarbide/oxynitride material designed for extreme-temperature applications. This research-phase material belongs to the family of advanced refractory ceramics and represents efforts to develop ultra-high-temperature materials that combine the thermal stability of hafnium-based compounds with the hardness and oxidation resistance contributions of osmium and nitrogen doping. While not yet in widespread industrial use, such materials are being investigated for next-generation hypersonic vehicles, advanced rocket engines, and high-temperature structural applications where conventional superalloys and ceramics reach their 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.
