Lanthanum oxide (also known as lanthana) is a chemical compound with the formula La2O3. It is a rare earth oxide and a white solid material with a cubic crystal structure. Lanthanum oxide is a high-temperature refractory material and is used in a variety of applications due to its excellent chemical stability and corrosion resistance. It is used as a material for making phosphors for use in cathode ray tubes and fluorescent lamps, as a dopant in semiconductor devices, and as a catalyst. It is also used in the production of ceramics and as a tracer in biological and chemical research.

Application

Lanthanum Oxide, also called Lanthana, high purity Lanthanum Oxide (99.99% to 99.999%) is applied in making special optical glasses to improves the alkali resistance of glass, and is used in La-Ce-Tb phosphors for fluorescent lamps and making special optical glasses, such as infrared-absorbing glass, as well as camera and telescope lenses, Low grade of Lanthanum Oxide is widely used in ceramics and FCC catalyst, and also as raw material for Lanthanum Metal production; Lanthanum Oxide is also used as a grain growth additive during the liquid phase sintering of Silicon Nitride and Zirconium Diboride.
