· Os3 Ca2 B5

Os₃Ca₂B₅ is an intermetallic ceramic compound combining osmium, calcium, and boron—a rare composition that places it at the intersection of refractory metals and boride ceramics. This is primarily a research-stage material studied for its potential in high-temperature structural applications, with the osmium providing exceptional thermal stability and the boride phase contributing hardness and oxidation resistance. Industrial adoption remains limited; the material's value lies in exploratory materials science for extreme environments where conventional superalloys or ceramics reach their performance ceiling.

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.
