Lanthanum Oxide

Cerium Oxide, also known as Cerium(IV) Oxide or Cerium Dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.

Cerium(III) Oxalate (Cerous Oxalate) is the inorganic cerium salt of oxalic acid, which is highly insoluble in water and converts to the oxide when heated (calcined). It is a white crystalline solid with the chemical formula of Ce2(C2O4)3. It could be obtained by the reaction of oxalic acid with cerium(III) chloride.

Gadolinium(III) Oxide (archaically Gadolinia) is an inorganic compound with the formula Gd2O3, which is the most available form of the pure gadolinium and the oxide form of one of the rare earth metal gadolinium. Gadolinium oxide is also known as gadolinium sesquioxide, gadolinium trioxide and Gadolinia. The color of the gadolinium oxide is white. Gadolinium oxide is odorless, not soluble in water, but soluble in acids.

Lanthanum Oxide, also known as a highly insoluble thermally stable Lanthanum source, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is suitable for glass, optic and ceramic applications, and used in some ferroelectric materials, and is a feedstock for certain catalysts, among other uses.

Neodymium(III) Oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd2O3. It is soluble in acid and insoluble in water. It forms very light grayish-blue hexagonal crystals.The rare-earth mixture didymium, previously believed to be an element, partially consists of neodymium(III) oxide. Neodymium Oxide is a highly insoluble thermally stable neodymium source suitable for glass, optic and ceramic applications. Primary applications include lasers, glass coloring and tinting, and dielectrics.Neodymium Oxide is also available in pellets, pieces, sputtering targets, tablets, and nanopowder.

Praseodymium (III,IV) Oxide is the inorganic compound with the formula Pr6O11 that is insoluble in water. It has a cubic fluorite structure. It is the most stable form of praseodymium oxide at ambient temperature and pressure.It is a highly insoluble thermally stable Praseodymium source suitable for glass, optic and ceramic applications. Praseodymium(III,IV) Oxide is generally High Purity (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) Powder lately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.

Scandium(III) Oxide or scandia is a inorganic compound with formula Sc2O3. The appearance is fine white powder of cubic system. It has different expressions like scandium trioxide, scandium(III) oxide and scandium sesquioxide. Its physico-chemical properties are very close to other rare earth oxides like La2O3, Y2O3 and Lu2O3. It is one of several oxides of rare earth elements with a high melting point. Based on present technology, Sc2O3/TREO could be 99.999% at highest. It is soluble in hot acid, however insoluble in water.

Yttrium Oxide, also known as Yttria, is an excellent mineralizing agent for spinel formation. It is an air-stable, white solid substance. It has a high melting point(2450°C), chemical stability, low coefficient of thermal expansion, high transparency for both visible (70%) and infrared (60%) light, low cut off energy of photons. It is suitable for glass, optic and ceramic applications.
