· JVASP-52641· Sr2Er2Al3Si5N11O3

Sr2Er2Al3Si5N11O3 is a rare-earth oxynitride ceramic combining strontium, erbium, aluminum, and silicon in a complex nitride-oxide matrix. This material belongs to the family of advanced ceramics engineered for high-temperature structural applications, and represents an active area of research rather than a widely commercialized compound. The inclusion of rare-earth elements (erbium) and the oxynitride structure suggest potential for thermal stability, oxidation resistance, and controlled mechanical properties at elevated temperatures—characteristics valuable in aerospace and energy applications where conventional ceramics face limitations.
