· Y4 Si4 O14

Y₄Si₄O₁₄ is a rare-earth silicate ceramic compound containing yttrium and silicon, belonging to the family of advanced oxide ceramics developed for high-temperature structural and functional applications. This material is primarily of research and development interest for aerospace and thermal management applications, where its rare-earth silicate composition offers potential advantages in thermal stability, oxidation resistance, and high-temperature strength compared to conventional silicates. The yttrium-silicon-oxygen system is studied as a candidate material for thermal barrier coatings, environmental barrier coatings (EBCs) for ceramic matrix composites, and next-generation refractory applications in demanding thermal environments.
