· HgAsO3

Mercuric arsenate (HgAsO₃) is an inorganic ceramic compound combining mercury and arsenic oxides, historically used as a pigment and in specialized chemical applications. Due to the toxicity of both mercury and arsenic constituents, this material has seen severely limited industrial use in modern engineering and has been largely phased out in favor of safer alternatives; its presence in databases is primarily of historical or research interest for understanding legacy materials or corrosion resistance in specific niche environments.

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.
