American Elements specializes in producing lanthanum strontium chromite (LSC) for fuel cell cathode and interconnect applications solid oxide fuel cell anode (Nickel Cermet) by SEM utilizing solid state processing to produce single phase perovskite structures with various doping levels and surface areas (SSA) for use in thin film layers. Upon firing, American Elements' Lanthanum Strontium Chromite will partially sinter to form well-defined necks and open gas paths to permit simultaneous gas and electrical transfer. Lanthanum Strontium Chromite has an excellent thermal expansion match with Yttria Stabilized Zirconia (YSZ) electrolytes. It is electronically conductive and has proven long term stability. Lanthanum Strontium Chromite belongs to a class of "A" site and "B" site doped perovskite structures with these properties. These include Lanthanum Strontium Ferrite (LSF), Lanthanum Strontium Cobaltite Ferrite (LSCF), Lanthanum Calcium Manganite (LCM), Lanthanum Strontium Manganite (LSM), and Lanthanum Strontium Gallate Magnesite (LSGM). Lanthanum Strontium Chromite is available as a powder for tape casting, air spray/thermal spray/plasma spray, extrusion and sputtering fuel cell applications and as an ink for screen printing. Strontium doping levels are available at 10% and 20% and as specified by customer. Oxygen starved compositions are available. American Elements provides guidance on firing parameters, doping levels, and thermal expansion matching with American Elements' electrolyte and interconnect fuel cell layers. Also see the product data sheet for LSC40-I.

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 it's Van der Waals radius is 200.pm. Lanthanum and compounds of Elemental LanthanumLanthanum 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. 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.

Strontium(Sr) atomic and molecular weight, atomic number and elemental symbolStrontium is a Block S, Group 2, Period 5 element. The number of electrons in each of Strontium's shells is 2, 8, 18, 8, 2 and its electronic configuration is [Kr] 5s2. In its elemental form strontium's CAS number is 7440-24-6. The strontium atom has a radius of 215.1.pm and it's Van der Waals radius is 200.pm. The non-radioactive isotopes of Strontium are not toxic. Strontium has low tech applications as an additive to flares and pyrotechnics because of the bright crimson flameStrontium Bohr Model produced by its salts. Strontium 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. It also has many high technology applications because of its high refractive index as a titanate in glass, as a "getter" in Elemental Strontiumelectron tubes and as a dopant for numerous perovskite formulations to produce cathodes for oxygen generation or solid oxide fuel cells. Historically the primary use of strontium was to produce CRT glass for color television and computer tubes. Strontium was first discovered by A. Crawford in 1790. Strontium was named after the Scottish town it was discovered in, Strontian. See Strontium research below.
