· JVASP-66551· Ba4HfOs

Ba4HfOs is a ceramic compound composed of barium, hafnium, and osmium—a complex oxide material that belongs to the family of high-entropy or multi-component ceramic oxides. This is a research-phase material rather than an established commercial product, developed to explore advanced ceramic properties at the intersection of refractory and functional oxide chemistry. Potential applications center on high-temperature structural applications, electronic or ionic conducting systems, or specialized catalytic environments where the combination of heavy transition metals (hafnium, osmium) and alkaline-earth stabilization (barium) could provide thermal stability, chemical inertness, or unique electrical properties unavailable in conventional ceramics.

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.
