· JVASP-66308· Ba4OsW

Ba₄OsW is an intermetallic compound containing barium, osmium, and tungsten. This is a research-phase material in the high-entropy alloy and refractory metal compound family, not yet established in widespread industrial production. The combination of osmium and tungsten—both refractory metals with extreme melting points—suggests potential for ultra-high-temperature structural applications, though current usage remains limited to materials science investigation and specialized laboratory studies.

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.
