High Purity Rare Earth Oxide 99.99% La2O3 Lanthanum Oxide
Basic information:
Lanthanum oxide is a white powder. Density 6.51 g/cm3. Melting point 2217℃. Boiling point 4200℃. Slightly soluble in water, easily soluble in acid to produce the corresponding salts.
Exposed to air, carbon dioxide and water are easily absorbed and gradually become lanthanum carbonate. The combination of burned lanthanum oxide with water gives off a large amount of heat.

Application:
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.
