Applications of Lanthanum

Lanthanum is employed in equipment like color televisions, fluorescent lamps, energy-saving lamps, and glasses. La2O2 is used to form special optical glasses (infrared adsorbing glass, camera, and telescope lenses). If added in small amounts it improves the malleability and resistance of steel. Lanthanum is used because the core material in carbon arc lamp electrodes. Lanthanum salts are included within the zeolite catalysts utilized in petroleum refining because they stabilize the zeolite at high temperatures. Lanthanum is also employed in large quantities in nickel-metal hydride rechargeable batteries.
