H4 O16 Cl4 Hg4
ceramic· H4 O16 Cl4 Hg4
This appears to be a mercury-chloride-oxygen compound, likely a chloride or oxychloride ceramic phase rather than a conventional engineering ceramic. Mercury-based compounds are extremely rare in modern materials engineering due to toxicity and volatility concerns; this composition may represent either a historical material, a laboratory synthesis, or a misidentified chemical formula. If this is a genuine ceramic phase, it would belong to the family of halide ceramics, though such materials are not typically specified for structural or functional engineering applications in current practice.

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.
