Lutetium Metal Powder Lu CAS 7439-94-3, The Hardest And Densest Metal Among Rare Earth Elements
Name: Lutetium metal powder, Lutetium powder Molecular formula: Lu
CAS: 7439-94-3 Molecular weight: 174.97
Description: Lutetium ranks 15th in the abundance of rare earth elements, and it is the rarest of lanthanides. In order to produce lutetium metal, alkali metal or alkaline earth metal can be used to reduce anhydrous lucl3 or LuF3. Only industrial pure lutetium can be obtained by calcium thermal reduction of fluoride. Generally, the purity of lutetium is 98%. In order to improve the purity of the reduced product, it is necessary to further sublimate and purify the smelting lutetium ingot.

Use: (1) Make some special alloys. For example, lutetium aluminum alloy can be used for neutron activation analysis. (2) Stable lutetium plays a catalytic role in petroleum cracking, alkylation, hydrogenation and polymerization. (3) The addition of yttrium iron or yttrium aluminum garnet improves some properties. (4) The material of magnetic bubble reservoir. (5) A kind of composite functional crystal, aluminum yttrium neodymium doped with lutetium tetraborate, belongs to the technical field of salt solution cooling growth crystal. Experiments show that the optical uniformity and laser performance of lutetium doped NYAB crystal are better than NYAB crystal. (6) It has been found that lutetium has potential applications in electrochromic displays and low dimensional molecular semiconductors. In addition, lutetium is also used in energy battery technology and phosphor activator.
