Calcium yttrium aluminate (CaYAl₃O₇) is a rare-earth-containing ceramic compound that belongs to the family of yttrium aluminate phases, which are valued for their thermal stability and refractory properties. This material is primarily investigated for high-temperature structural and functional applications where thermal shock resistance and chemical inertness are critical, particularly in advanced ceramic matrix composites, thermal barrier coatings, and specialized refractories. It competes with other yttrium aluminate phases and conventional refractories by offering improved phase stability at elevated temperatures, making it a candidate for next-generation aerospace and industrial furnace applications.
