· JVASP-61588· Y3Sc2Al3O12

Y₃Sc₂Al₃O₁₂ is a rare-earth aluminate ceramic compound combining yttrium, scandium, and aluminum oxides, belonging to the family of garnets and mixed-oxide ceramics used in specialized optical and thermal applications. This material is primarily investigated in research contexts for high-temperature optical coatings, luminescent devices, and thermal barrier applications where its rare-earth composition provides enhanced refractive properties and thermal stability. Compared to conventional ceramics, the scandium and yttrium dopants enable tuned optical transparency and improved performance in extreme-temperature environments, making it attractive for next-generation photonics and aerospace thermal management systems.
