Applications

1:Lanthanum Oxide, also called Lanthana, high purity Lanthanum Oxide (99.99% to 99.999%).
 

2:Be applied in making special optical glasses to improves the alkali resistance of glass.
 

3: 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.
 

4:Low grade of Lanthanum Oxide is widely used in ceramics and FCC catalyst, and also as raw material for Lanthanum Metal production.

5:Lanthanum Oxide is also used as a grain growth additive during the liquid phase sintering of Silicon Nitride and Zirconium Diboride.
