YAlO₂ (yttrium aluminum oxide) is an advanced ceramic compound belonging to the family of rare-earth aluminate ceramics. It is primarily of research and specialized industrial interest, valued for its thermal stability, chemical inertness, and potential as a refractory material or high-temperature component. Applications include high-temperature structural ceramics, thermal barrier coatings, and specialized optical or electronic components where rare-earth doping and phase stability are advantageous compared to conventional aluminas.
