Lanthanum, atomic no.: 57, symbol as La, weight at 138.91, is the first element in the rare earth or lanthanide series. It is the model for all the other trivalent rare earths. After cerium, it is the second most abundant of the rare earths.
Lanthanum-rich lanthanide compounds have been used extensively for cracking reactions in FCC catalysts, especially to manufacture high-octane gasoline from heavy crude oil.
Lanthanum-Rich Rare Earth metals play the important roles in hydrogen storage bettaries.
It is utilized in green phosphors based on the aluminate (La0.4Ce0.45Tb0.15)PO4.
Lanthanide zirconates are used for their catalytic and conductivity properties and lanthanum stabilized zirconia has useful electronic and mechanical properties.
It is utilized in laser crystals based on the yttrium-lanthanum-fluoride (YLF) composition.
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
Lanthanum Oxide, also called Lanthana, Lathnaum Oxide is widely used in ceramics and FCC catalyst, and also as raw material for Lanthanum Metal production. High purity 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.
