Lutetium Oxide (Lu2O3), also called lutecia, is a cubic compound of lutetium. It is a lanthanide oxide, also known as a rare earth. Lutetium Oxide is white in color and insoluble in water. Due to the nature of oxide compounds, Lutetium Oxide is not conductive to electricity. However, it produces lutetium tantalate, the densest white material known, and is frequently used for x-ray phosphors. It is also insoluble in water solutions but soluble in all common acids and is useful for ceramic applications. Lutetium, atomic no. 71, symbol Lu, weight at 174.97, is the last member of the rare earth series. Unlike most rare earths it lacks a magnetic moment. It also has the smallest metallic radius of any rare earth. It is perhaps the least naturally abundant of the lanthanides. It is the ideal host for x-ray phosphors because it produces the densest known white material, lutetium tantalate (LuTaO4). It is utilized as a dopant in matching lattice parameters of certain substrate garnet crystals, such as indium-gallium-garnet (IGG) crystals due its lack of a magnetic moment.
Lutetium oxide or lutetium is a highly insoluble, thermally stable source of lutetium for glass, optical and ceramic applications. Lutetium oxide is a solid cubic compound of lutetium that is white in color. Most volumes of lutetium oxide are typically available immediately. Ultra-high purity, high purity, submicron and nano powder forms can be considered. Lutetium is used in high-purity (99.999%) lutetium oxide (Lu2O3) powder X-ray phosphorescence because it produces the highest density white material known, lutetium tantalate (LuTaO4). It is used as a dopant to match the lattice parameters of certain substrate garnet crystals, such as indium gallium garnet (IGG). Oxides do not conduct electricity. However, certain chalcogenide structured oxides are electrically conductive and can be used as cathodes in solid oxide fuel cells and oxygen generation systems. Rare earth oxide compounds are basic anhydrides and therefore can react with acids and strong reducing agents in redox reactions. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, which allows them to be used in ceramic structures (as simple as producing clay bowls) to advanced electronics and lightweight structural components in aerospace and electrochemical applications (e.g., fuel cells) where they exhibit ionic conductivity. Lutetium oxide is also available as granules, flakes, powders, sputtering targets, and flakes.
