Hg4 O8
ceramic· Hg4 O8
Hg₄O₈ is a mercury oxide ceramic compound that exists primarily as a research material rather than a widely commercialized engineering ceramic. This compound belongs to the family of mercury-based oxides and represents an intermediate oxidation state phase in the mercury-oxygen system. While mercury oxides have historical significance in chemical synthesis and laboratory applications, Hg₄O₈ has limited practical engineering use due to mercury's toxicity concerns, regulatory restrictions, and the availability of safer alternative materials for most modern applications.

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.
