· JVASP-66324· Ba4CoOs

Ba₄CoOs is a complex metallic compound combining barium, cobalt, and osmium—a research-phase material that belongs to the family of high-entropy intermetallic compounds. This material is primarily of academic and exploratory interest rather than established industrial production, with potential applications in high-temperature structural applications or specialized electronic/magnetic devices where the combination of refractory metals offers unusual property combinations.

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.
