Yttrium is a silver-grey metallic element occurring in gadolinite, xenotime and other minerals. It takes its name from Ytterby, a village in Sweden near Vauxholm, which is the site of a quarry which yielded many unusually minerals containing rare earths and other elements. The German chemist Friedrich Wöhler (1800 - 1882) obtained the impure element in 1828 by reduction of the anhydrous chloride with potassium. The metal is now produced commercially by reduction of the fluoride with calcium metal.
