High Purity ChunkAmerican Elements specializes in producing high purity Lanthanum Chunk using crystallization, solid state and other ultra high purification processes such as sublimation. Standard Chunk pieces are amorphous uniform pieces ranging in size from 5-15 mm. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into granules, rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. See research below. We also produce Lanthanum as rod, pellets, powder, pieces, disc, ingot, wire, and in compound forms, such as oxide. Other shapes are available by request.

Lanthanum (La) atomic and molecular weight, atomic number and elemental symbol 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 its 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 EarthsLanthanum Bohr Model. 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. Elemental LanthanumLanthanum 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. Purdue University researchers recently used Lanthanum Aluminate nanowires in next generation transistors that may eventually replace silicon transistors. Lantahanum is found in monazite and bastnasite. The name Lanthanum originates from the Greek word Lanthaneia which means 'To lie hidden'. See Lanthanum research below.
