Barium diselenide (BaSe₂) is an inorganic ceramic compound belonging to the metal chalcogenide family, characterized by a barium cation bonded to selenium anions in a defined crystal structure. This material is primarily investigated in research contexts for semiconductor and optoelectronic applications, where its electronic band structure and thermal properties make it relevant to photovoltaic devices, infrared detectors, and solid-state physics studies. BaSe₂ is notable within the chalcogenide ceramics family for its potential in niche high-temperature or radiation-resistant applications, though it remains less established in mainstream industrial production compared to more conventional oxide ceramics.
