Lanthanum aluminate (LaAlO3) is a perovskite-structured oxide ceramic known for its high hardness, refractory properties, and excellent chemical stability at elevated temperatures. It is primarily used in advanced electronics and photonics applications, particularly as a substrate material for thin-film deposition and in optical devices, as well as in high-temperature structural applications where chemical inertness and thermal stability are critical; its 2D electron gas properties at heterointerfaces with SrTiO3 have made it especially valuable in emerging condensed-matter physics research and next-generation electronic devices.
