· JVASP-26727· BaHg2Cl2O2

BaHg2Cl2O2 is an inorganic ceramic compound containing barium, mercury, chlorine, and oxygen—a mixed-halide oxide that belongs to the family of complex metal halide ceramics. This is primarily a research and specialty material rather than a widely commercialized engineering ceramic; it represents the type of compound explored for potential applications in electrochemistry, optics, or solid-state chemistry where unusual crystal structures and ionic properties may offer advantages. The material's notable combination of density and elastic properties makes it of interest in research contexts where mercury-containing inorganic phases are investigated, though environmental and toxicity considerations typically limit practical industrial deployment compared to mercury-free alternatives.
