Lutetium(III) oxide, a white solid, is a cubic compound of lutetium sometimes used in the preparation of specialty glasses. It is also called lutecia. It is a lanthanide oxide. [Lutetium Oxide. 1997-2007. Metall Rare Earth Limited.]

History

In 1879, Jean-Charles-Galissard de Margnac (1817-1894), a French chemist, claimed to have discovered ytterbium, but actually he had found a mixture of elements. In 1907, a French chemist Georges Urbain (1872-1938) reported that ytterbium was a mixture of two new elements and not a single element. Two more chemists came to the same conclusion. They were from germany, Karl Auer (1858-1929) and America, Charles James (1880-1926). The two compounds they discovered were neoytterbium and lutecium. However, none of these chemists actually dealt with pure lutetium. The compound they found was usually lutetium oxide. [Lutetium. 2005-2006. Bookrags.]

Uses

The product of Lu2O3 and PdO (formed at high pressure and temperature in the presence of potassium chlorate) has a potential use in superconducting materials. [Lutetium (III) oxide. 2007. Sigma Aldrich.] Lutetium(III) oxide is an important raw material for laser crystals. It also has specialized uses in ceramics, glass, phosphors, and lasers. Lutetium(III) Oxide is used as a catalyst in cracking, alkylation, hydrogenation, and polymerization. [Lutetium Oxide. 1997-2007. Metall Rare Earth Limited.]
