· JVASP-10291· SeS2N2O2

SeS2N2O2 is an inorganic ceramic compound containing selenium, sulfur, nitrogen, and oxygen elements. This material represents an emerging class of mixed-anion ceramics that combines properties from selenide, sulfide, nitride, and oxide chemistries, making it a subject of research interest for applications requiring tailored mechanical and thermal characteristics. While not yet widely commercialized, materials in this compositional family are being explored for advanced structural applications where conventional ceramics may be limited by brittleness or thermal sensitivity.
