· JVASP-11196· Ba2SiSe4

Ba₂SiSe₄ is an inorganic ceramic compound composed of barium, silicon, and selenium—a mixed-anion ceramic belonging to the family of selenide materials. This compound is primarily of research and development interest rather than established industrial production, with potential applications in infrared optics and photonic materials where its wide bandgap and thermal properties may be advantageous compared to conventional oxide ceramics or semiconductors.
