· HgSeO3

Mercury selenite (HgSeO3) is an inorganic ceramic compound containing mercury, selenium, and oxygen. This is a specialized material primarily of research and historical interest rather than a mainstream engineering ceramic. It belongs to the family of heavy metal oxysalts and has been investigated in optics, semiconductors, and crystal physics research, though its toxicity and specialized properties limit widespread industrial adoption compared to conventional 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.
