About Lanthanum Metal

High Purity (99.999%) Lanthanum (La) MetalLanthanum Metal is available as disc, granules, ingot, pellets, pieces, powder , rod, sputtering target, wire, and in numerous other forms and custom shapes. 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. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Ultra high purity and high purity forms also include metal powder, submicron powder and nanoscale, quantum dots, targets for thin film deposition, pellets for evaporation and single crystal or polycrystalline forms. Elements can also be introduced into alloys or other systems as fluorides, oxides or chlorides or as solutions. Lanthanum metal is generally immediately available in most volumes. Lanthanum is used in cracking catalysts, advanced ceramics and in green phosphors. Lanthanide zirconates and lanthanum strontium manganites are used for their catalytic and conductivity properties. Lanthanum's ability to bind with phosphates in water creates uses in water treatment. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Lanthanum Bohr ModelThe number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d1 6s2. The lanthanum atom has a radius of 187 pm and a Van der Waals radius of 240 pm. Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance.Elemental Lanthanum It is a soft, malleable, and ductile metal that oxidizes easily in air. Lanthanum is the first element in the rare earth or lanthanide series. It is the model for all the other trivalent rare earths and it is the second most abundant of the rare earths after cerium. Lanthanum is found in minerals such as monazite and bastnasite. The name lanthanum originates from the Greek word Lanthaneia, which means 'to lie hidden'.
