· JVASP-97579· Hg3AsO4

Hg₃AsO₄ is an inorganic ceramic compound containing mercury, arsenic, and oxygen, belonging to the family of heavy metal oxide ceramics. This material is primarily of research and historical interest rather than a standard engineering material; it appears in materials science literature related to mercury-arsenic systems and their crystalline phases. While not widely deployed in modern industrial applications due to toxicity concerns with both mercury and arsenic constituents, compounds in this family have been investigated for specialized applications in electronic ceramics, photovoltaic research, and historically in certain optical or detector systems where heavy metal content provided specific functional properties.

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.
