Ba₄YO₈ is a rare-earth barium yttrium oxide ceramic compound belonging to the family of mixed-metal oxides with potential applications in high-temperature and electrochemical systems. This material is primarily explored in research contexts for thermal barrier coatings, solid-state electrolytes, and advanced refractory applications where chemical stability and thermal properties are critical. Its layered crystal structure and rare-earth doping make it of particular interest for solid oxide fuel cell (SOFC) electrolytes and other ionic-conductor applications where yttrium-containing ceramics offer advantages over conventional stabilized zirconia systems.

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.
