CaY2O4 is a calcium yttrium oxide ceramic compound belonging to the rare-earth oxide family, combining alkaline-earth and lanthanide chemistry. This material is primarily studied for high-temperature applications and optical/photonic systems where rare-earth doping and thermal stability are required. It offers potential advantages in refractory coatings, phosphor hosts for lighting, and as a matrix material in composite systems where the combination of calcium and yttrium oxides provides enhanced thermal conductivity or luminescent properties compared to single-component alternatives.
