Application of Lanthanum Oxide La2O3 Powder :
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.

Storage Condition of  Lanthanum Oxide La2O3 Powder :

Generally, commercial products are added with polymerization inhibitors. Store in a cool, ventilated warehouse. Keep away from fire and heat. The storage temperature should not exceed 30℃. The packaging needs to be sealed and not in contact with air. It should be stored separately from oxidants, acids, alkalis, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
