American Elements' Nanometal, nanofoil manufacturing unit produces ultra thin foil as thin as only 50 nm thick in diameters up to 910 mm. Typically, foils are in thicknesses from 20 nm to 1000 nm, 1 micron, 2 micron, and up to a few microns thick. Nanometal™ ultra thin foil can also be produced on a substrate with a parting agent to permit removal by floating and can then be mounted on frames. Frames may be washers, rings, or more-complicated assemblies. For foils >1 micron thick see our Lanthanum Foil page. We also produce Lanthanum as rods, powder and plates. Other shapes are available by request.
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.
