product details

Lanthanum Oxide

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 also in La-Ce-Tb phosphors for fluorescent lamps. Low grade of Lanthanum Oxide is widely used in ceramics and FCC catalyst, and also as raw material for Lanthanum Metal production.

Formula La2O3 CAS No. 1312-81-8 Molecular Weight 325.82 Appearance White Solubility Insoluble in water, moderately soluble in strong mineral acids Stability Strongly hygroscopic
