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.[1]
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. [2]
Uses
The product of Lu2O3 and PdO (formed at high pressure and temperature in the presence of of potassium chlarate) has a potential use in superconducting materials and being used as a goechemical.[3] 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.[4]
Hazards
Lutetium(III) oxide is an irritant. It causes irritation to the eyes, respiratory system, and skin.[5]
First Aid Measures
For oral exposures, wash mouth out with water for a conscious person and call a physician.
For inhalation exposure, take person to fresh air. If the person is not breathing, perform CPR. If the person is having difficultly breathing , give the person oxygen.
For skin exposure, wash the affected skin with soap and profuse amounts of water immediately.
For eye exposure, flush the person's eyes with profuse amounts
of water for at least 15 minutes immediately.[6]
