· Sr2 Er2 Al3 Si5 N11 O3

Sr₂Er₂Al₃Si₅N₁₁O₃ is an oxynitride ceramic compound combining strontium, erbium, aluminum, and silicon with nitrogen and oxygen in its crystal structure. This material belongs to the rare-earth oxynitride family, primarily explored in research and advanced applications where thermal stability, optical properties, or dielectric performance are needed in harsh environments. The incorporation of erbium (a lanthanide) and the mixed anionic framework (nitrogen and oxygen) distinguish it from conventional silicate ceramics, making it a candidate for next-generation high-temperature ceramics, optical phosphors, or specialized semiconductor applications.
