CaAsO3
ceramic· CaAsO3
Calcium arsenate (CaAsO3) is an inorganic ceramic compound composed of calcium, arsenic, and oxygen. It belongs to the family of arsenate ceramics and is primarily encountered in industrial and environmental contexts rather than as a deliberately engineered structural material. This compound is historically significant in pesticide formulations and wood preservation applications, though its arsenic content raises toxicological concerns that have limited modern engineering adoption in favor of safer alternatives.

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.
