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.
