Lutetium brand, chemical structure
General characteristics
The Lutetia is in the third group of the table of Mendeleev, where indicated by the chemical symbol Lu. Atomic number 71. Refers to the lanthanides. the atomic weight 174,967. As an impurity is found in the deposits of gadolinite. Modern industry takes the element, separating it from other lanthanides by ion exchange, extraction, and fractional crystallization. Calcium can restore LuF3 to metal. In its pure form is a soft, silvery metal. In the series of the lanthanides it is the most severe and resistant to heat. It t° melting 1663 °C, among the rare earth elements is the maximum.

Chemical properties
Under normal conditions in air and protected by a strong oxide film. Forms compounds with sulphur, Halogens and other nonmetals it begins when heated above 400 °C. Readily soluble in inorganic acids with formation of salts. With hydrofluoric acid and its salts, it forms fluorides. Hydroxide, Lu (OH)3 obtained by hydrolysis of soluble salts.
Application
The other element alloyed heat-resistant Nickel-chromium alloys to improve their processability and durability. Alloys of lutetium rolled sheet, round, wire, etc. the Lutetia is part of heat-resistant metal oxide conducting ceramics. Its alloys are magnetic materials, so are used as information carriers in cylindrical magnetic domains. Oxide of Lu2 O3 is included in the composition of the absorbing rods of nuclear boilers and as activation detector. The definition of the spectral analysis of impurities of oxides of lutetium, europium, samarium normalizes 23 GOST862.3−79.
