Yttrium


Yttrium was discovered, in 1794, by the Scandinavian chemist Johan Gadolin, through the treatment of an ore obtained in Ytterby, Sweden. This small city would give the name to this element as well as the others obtained from the same ores, as terbium, erbium and ytterbium. Yttrium was isolated for the first time in its metallic state, in 1828, by Wohler. Although it is not a lanthanide, it is frequently considered to belong to the rare-earth family, due to the likeness of both its chemical and metallurgical properties. For a long time there were no applications of the element, due to the difficulty of separating from the rare earth. However, with the recent improvement of these techniques, its study has been deepened, revealing new applications.
