· OsTaOFN

OsTaOFN is an advanced ceramic compound combining osmium, tantalum, oxygen, and nitrogen, representing a refractory oxide-nitride material designed for extreme-temperature and high-performance applications. This material belongs to the class of complex transition metal ceramics and appears to be primarily a research-phase composition rather than a widely commercialized grade. The addition of nitrogen to the osmium-tantalum oxide system is intended to enhance hardness, thermal stability, and chemical resistance beyond conventional refractory oxides, making it of interest for applications demanding both thermal and mechanical performance in corrosive or wear-intensive environments.

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.
