· BaAsO3

Barium arsenate (BaAsO3) is an inorganic ceramic compound composed of barium, arsenic, and oxygen, belonging to the class of metal arsenate ceramics. This material is primarily of research and specialized industrial interest, used in optical applications, phosphor development, and high-temperature ceramic systems where arsenic-containing compounds are tolerated. BaAsO3 is notable in materials science for its crystal structure and potential optical properties, though its toxicity concerns from arsenic content limit widespread commercial adoption compared to non-arsenic alternatives like barium titanate or barium zirconate.

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.
