ceramic· JVASP-116693· KBa2Bi2O9
KBa₂Bi₂O₉ is a complex oxide ceramic compound containing potassium, barium, and bismuth. This material belongs to the family of bismuth-based ceramics, which are primarily investigated for photocatalytic and optoelectronic applications due to bismuth's electronic properties and visible-light activity. While not yet widely deployed in mainstream industrial production, compounds in this material class show promise for environmental remediation (water purification, air treatment) and potentially for photovoltaic or light-harvesting devices where visible-light responsiveness is advantageous over traditional wide-bandgap 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.
