Lanthanum oxide (Cat No.: M048023) is a white, hygroscopic solid composed of lanthanum in the +3 oxidation state and oxygen. It is a basic, refractory material that absorbs moisture and carbon dioxide from the air. La₂O₃ is widely used in ceramics, optics, phosphors, and electronic devices, particularly in manufacturing high-refractive-index glass, catalysts, and dielectric materials. It also serves as a precursor for lanthanum-based compounds and is valuable in fuel cells, carbon arc lamps, and rare earth element research due to its unique electronic properties.
