Metal scandium

Technical characteristics of scandium

It is an element of the 4th period table of chemical elements, which is indicated as Sc. Atomic number 21. Its content in the solid rocks of approximately 9.5 g/t, significant resources are concentrated in the Carboniferous deposits in the form of oxides (scandium beryl, cassiterite, fluorite). Technology of extraction of this element is associated with the processing of coal. Lightweight metal scandium is characterized by a silver color with a yellow tinge, melting point 1541 °C and heat of fusion is 15.8 kJ/mol. Is a typical dispersed element, a weak paramagnetic material, the lattice structure of α-Sc of hexagonal due to its flexibility easily to different types of treatment. The most common alloy of scandium and aluminum. As a Supplement he gives the alloy good ductility and toughness. The properties of this metal was predicted by D. I. Mendeleev, and opened it in 1879 Swedish chemist Nielsen and was named in honor of Scandinavia.

Application

Scandium is widely used in metallurgy (at the alloying heat-resistant steels), in medicine, microelectronics, electrical engineering, nuclear power engineering, production of refractory materials, lasers, phosphors, spectrometers and solar cells, details of the MHD generators. A radioactive isotope 46 Sc with a half life up to 84 days, it is used to treat tumors, and in the petrochemical industry and as a test mark" to the technological processes. Aluminium alloy with scandium has a high ductility and strength, is used for the production of various products.
