HgCl
ceramic· HgCl
Mercury(II) chloride (HgCl₂), commonly known as corrosive sublimate, is an inorganic ceramic compound historically classified as a heavy metal halide salt. Once widely used in chemical synthesis, disinfection, and analytical chemistry, its industrial applications have largely been phased out or severely restricted due to mercury's toxicity and environmental persistence. Modern engineering interest in HgCl is primarily in historical materials analysis, specialized analytical instrumentation, and legacy equipment remediation rather than new design 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.
