Scandium is a chemical element with the symbol Sc and atomic number 21. A type of d-block metallic element of silvery-white color, which has historically been classified as a rare earth element, together with yttrium and lanthanides. It was discovered in 1879 by the spectral analysis of euxenite and gadolinite minerals from Scandinavia.
Scandium is present in most deposits of rare earth compounds and uranium but is extracted from these minerals only in some mines around the world. Due to the lack of availability and difficulty in the preparation of scandium metal, which was first performed in 1937, the scandium applications were not developed until the 1970s. The positive effects of scandium on aluminum alloys over the years were discovered. 70, and its use in such alloys remains its only important application. The world market for scandium oxide is around 10 tons per year.
