· JVASP-57529· KHg2SCl3O3

KHg2SCl3O3 is an inorganic ceramic compound containing mercury, sulfur, chlorine, and oxygen, representing a mixed-halide mercury sulfide-based ceramic system. This is a specialized research-phase material rather than an established commercial ceramic; compounds in this family are primarily of academic and theoretical interest for studying mercury coordination chemistry and halide-based inorganic frameworks. Engineers would consider this material only in niche applications requiring unique electronic, optical, or chemical properties enabled by its specific mercury-halide-sulfide structure, though practical use remains limited due to toxicity concerns and lack of established manufacturing or application routes.
