Product Code : RE-La-5N-CU
Lanthanum (La) is is a soft, ductile, silvery-white metal that belongs to the lanthanide series. Lanthanum has numerous applications as additives in glass, catalysts, ignition elements in lighters and torches, carbon arc lamps for studio lights and projectors, electron cathodes, gas tungsten arc welding electrodes, scintillators, and other things.
At temperatures above 440 ° C lanthanum burns to lanthanum oxide (La2O3). The formation of hydrogen in cold water is slow, in warm water a rapid reaction to the hydroxide. In dilute acids, lanthanum dissolves under evolution of hydrogen. With many elements it reacts directly in the heat, with halogens even at room temperature. Lanthanum and hydrogen form a black, water-sensitive unstoichiometric hydride.
ATT specializes in producing Lanthanum as rolled sheets in various thicknesses and sizes. Most sheets are produced from cast ingots for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thickness can range from 0.04" to 0.25" for all metals. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. ATT specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. Lanthanum metal is predominantly used in the production of mischmetal and steel additives but is also important in the production of hydrogen storage alloys for nickel-metal hydride (NiMH) batteries. ATT also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. Typical and custom packaging is available. We also produce Lanthanum as rods, powder and plates. Other shapes are available by request.

Lanthanum (La) Metal Application
Lanthanum metal has no commercial uses. However, its alloys have a variety of uses. A lanthanum-nickel alloy is used to store hydrogen gas for use in hydrogen-powered vehicles. Lanthanum is also found in the anode of nickel metal hydride batteries used in hybrid cars.
Lanthanum is an important component of mischmetal alloy (about 20%). The best-known use for this alloy is in 'flints' for cigarette lighters.
'Rare earth' compounds containing lanthanum are used extensively in carbon lighting applications, such as studio lighting and cinema projection. They increase the brightness and give an emission spectrum similar to sunlight.
Lanthanum(III) oxide is used in making special optical glasses, as it improves the optical properties and alkali resistance of the glass. Lanthanum salts are used in catalysts for petroleum refining.
The ion La3+ is used as a biological tracer for Ca2+, and radioactive lanthanum has been tested for use in treating cancer.
