· JVASP-71477· Y2BeOs

Y2BeO₃ is an yttrium beryllium oxide ceramic compound belonging to the family of rare-earth beryllium oxides. This material is primarily of research and specialized industrial interest, valued for its combination of low density, high thermal stability, and potential use in high-performance applications where beryllium's lightweight properties and beryllia's thermal conductivity are advantageous. The material appears in niche aerospace, nuclear, and advanced thermal management applications, though it remains less common than conventional ceramics due to beryllium's toxicity concerns and processing complexity.
