LaO

Lanthanum oxide (La₂O₃) is an inorganic ceramic compound belonging to the rare-earth oxide family, valued for its high refractive index, thermal stability, and ionic conductivity. It is widely used in optical coatings, phosphors for display technologies, and as a dopant or component in advanced ceramics and glass formulations; it also serves as a catalyst support in chemical processing and emerging applications in solid-state electrolytes for energy storage. Engineers select LaO-based materials when high-temperature stability, optical transparency, or ionic transport properties are critical, particularly in precision optics and solid-state energy devices where alternative oxides may lack sufficient performance.
