Barium disulfide (BaS₂) is an inorganic ceramic compound belonging to the chalcogenide family, characterized by ionic bonding between barium cations and sulfide anions. This material is primarily of research and specialized industrial interest rather than a commodity ceramic, with applications in optical systems, solid-state chemistry, and emerging semiconductor research where its optical and electronic properties are leveraged.
