· JVASP-15293· ErSi2Os2

ErSi₂O₅ is an erbium silicate ceramic compound belonging to the rare-earth oxide family, characterized by a dense crystalline structure. This material is primarily of research interest for high-temperature applications where thermal stability and refractory properties are critical, particularly in aerospace and advanced materials development. Erbium silicates are explored as thermal barrier coatings and matrix materials in ceramic composites due to their potential thermal shock resistance and oxidation stability at elevated temperatures.
