Lanthanum Applications





Applications

Molten lanthanum is used for plutonium extraction from liquid uranium. It is the contact point of rare element and atomic industries.

La2O3 has more extensive applications. It is a white amorphous powder; insoluble in water improves the alkali resistance of glass. The Kodak's camera objectives contain from 20 to 40% La2O3. Lanthanum additives made possible to decrease camera objectives dimensions and to improve colour photos quality at the same luminosity. It was used in field-type optical devices.
