· Ca2 Y4 O8

Ca₂Y₄O₈ is a rare-earth oxide ceramic compound belonging to the family of yttrium-calcium mixed oxides, which are typically investigated for their thermal and optical properties in advanced ceramic applications. This material is primarily of research interest in photonics, phosphor technology, and high-temperature structural ceramics, where rare-earth oxide combinations are explored for luminescence, thermal barrier coatings, and specialized refractory applications. Its appeal over simpler oxides lies in the ability to tailor properties through rare-earth doping and mixed-cation structures, making it relevant for applications requiring thermal stability and potential optical functionality.
