White Rare Earth Lanthanum Oxide Powder 99.99% for special optical glasses

Lanthanum Oxide 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.

Usage

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.
