· JVASP-12474· Hg3Cl2O2

Hg₃Cl₂O₂ is a mercury-based inorganic ceramic compound containing mercury, chlorine, and oxygen. This material belongs to a specialized family of mercury halide oxides that have historically appeared in chemical and materials research, though practical industrial applications remain limited due to mercury's toxicity and regulatory restrictions. The compound's notable density and moderate elastic stiffness suggest potential research interest in specialized applications, but engineers should carefully evaluate regulatory, safety, and environmental constraints before considering this material for new designs.
