Ferrite StructureAmerican Elements specializes in producing Lanthanum Strontium Ferrite (LSF) for fuel cell cathode applications 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 Ferrite will partially sinter to form well-defined necks and open gas paths to permit simultaneous gas and electrical transfer. Lanthanum Strontium Ferrite has an excellent thermal expansion match with Yttria Stabilized Zirconia (YSZ) electrolytes. It is highly electronically conductive and has proven long term stability. Lanthanum Strontium Ferrite belongs to a class of "A" site and "B" site doped perovskite structures with these properties. These include Lanthanum solid oxide fuel cell anode (Nickel Cermet) by SEMStrontium Manganite (LSM), Lanthanum Strontium Cobaltite Ferrite (LSCF), Lanthanum Calcium Manganite (LCM), Lanthanum Strontium Chromite (LSC), and Lanthanum Strontium Gallate Magnesite (LSGM). Lanthanum Strontium Ferrite 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.

See more Iron products. Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. Iron Bohr ModelThe iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole. Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite.Elemental Iron Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger.

Lanthanum Bohr ModelThe number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d1 6s2. The lanthanum atom has a radius of 187 pm and a Van der Waals radius of 240 pm. Lanthanum was first discovered by Carl Mosander in 1838. In its elemental form, lanthanum has a silvery white appearance.Elemental Lanthanum It is a soft, malleable, and ductile metal that oxidizes easily in air. Lanthanum is the first element in the rare earth or lanthanide series. It is the model for all the other trivalent rare earths and it is the second most abundant of the rare earths after cerium. Lanthanum is found in minerals such as monazite and bastnasite. The name lanthanum originates from the Greek word Lanthaneia, which means 'to lie hidden'.

Strontium Bohr ModelThe number of electrons in each of Strontium's shells is [2, 8, 18, 8, 2] and its electron configuration is [Kr] 5s2. The strontium atom has a radius of 215 pm and a Van der Waals radius of 249 pm. Strontium was discovered by William Cruickshank in 1787 and first isolated by Humphry Davy in 1808. In its elemental form, strontium is a soft, silvery white metallic solid that quickly turns yellow when exposed to air. Elemental StrontiumCathode ray tubes in televisions are made of strontium, which are becoming increasingly displaced by other display technologies pyrotechnics and fireworks employ strontium salts to achhieve a bright red color. Radioactive isotopes of strontium have been used in radioisotope thermoelectric generators (RTGs) and for certain cancer treatments. In nature, most strontium is found in celestite (as strontium sulfate) and strontianite (as strontium carbonate). Strontium was named after the Scottish town where it was discovered.
