· JVASP-85570· Hg2ClO

Hg2ClO is a mercury-based halide ceramic compound, representing a specialized inorganic ceramic in the mercury chloride family. This material is primarily encountered in historical applications and specialized research contexts rather than modern mainstream engineering, where it has been studied for its ionic conduction properties and dense crystalline structure. Engineers may encounter specifications for this compound in legacy optical systems, historical mercury cell applications, or materials research focused on halide ceramics, though it has largely been superseded by safer, more stable alternatives in contemporary industrial practice.
