LaSiON2

LaSiON₂ is an oxynitride ceramic compound combining lanthanum, silicon, oxygen, and nitrogen in its crystal structure. This material belongs to the family of rare-earth silicon oxynitrides, which are primarily investigated for high-temperature structural applications where conventional oxides lose strength or chemical stability. Industrial adoption remains limited as this is largely an experimental material; research focuses on aerospace thermal protection, engine components, and extreme-environment applications where the oxynitride structure offers potential advantages in oxidation resistance and mechanical retention at elevated temperatures compared to pure silicates.
