Lanthanum Oxide is a highly insoluble thermally stable Lanthanum source suitable for glass, optic and ceramic applications. Lanthanum oxide is a white, odorless solid that is soluble in dilute acid but insoluble in water. Ultimately, Lanthanum oxide converts to lanthanum hydroxide with the absorption of moisture under atmosphere. Lanthanum Oxide is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. 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. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems.
Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containing at least one oxygen anionand one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Lanthanum Oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). See Nanotechnology for more nanotechnology applications information. Additional technical, research and safety (MSDS) information is available.
Lanthanum is a Block F, Group 3, Period 6 element. The number of electrons in each of Lanthanum's shells is 2, 8, 18, 18, 9, 2 and its 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 and compounds of Lanthanum are somewhat toxic. 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. The name Lanthanum originates from the Greek word Lanthaneia which means 'To lie hidden'. See Lanthanum research below.
