· JVASP-49409· Ba2HgS3

Ba2HgS3 is an inorganic ceramic compound composed of barium, mercury, and sulfur, belonging to the family of metal sulfide ceramics with potential semiconductor or optoelectronic properties. This material is primarily of research interest rather than established industrial use, studied for applications in photonic devices, infrared optics, or solid-state chemistry where the combination of heavy metal (mercury) and chalcogen (sulfur) bonding offers unique electronic or optical characteristics compared to simpler binary sulfides.
