Lanthanum Metal is available as disc, granules, ingot, pellets, pieces, powder
, rod, sputtering target, wire, and in numerous other forms and custom shapes. See safety data and research below. 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. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Lanthanum is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe] 5d1 6s2. In its elemental form lanthanum 's CAS number is 7439-91-0. The lanthanum atom has a radius of 187.pm and it's Van der Waals radius is 200.pm. Lanthanum is one of the products manufactured and distributed under the tradename AE Rare Earths. Lanthanum 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 is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Lanthanum-rich lanthanide compositions have been used extensively for cracking reactions in FCC catalysts, especially to manufacture low-octane fuel for heavy crude oil. |
