· JVASP-35207· Sr6Y2Al4O15

Sr6Y2Al4O15 is a strontium-yttrium aluminate ceramic compound, part of the rare-earth aluminate family of materials developed primarily for high-temperature structural and functional applications. This material is of particular interest in research contexts for thermal barrier coatings, refractory applications, and advanced ceramics where thermal stability and resistance to chemical degradation are critical; its incorporation of rare-earth elements (yttrium) and alkaline-earth elements (strontium) provides enhanced phase stability and oxidation resistance compared to conventional alumina-based alternatives.
