Scandium was discovered in 1879 by L.F. Nilson and takes its name from the Latin word "Scandia", meaning "Scandinavia". Scandium is a soft, silvery white metal. It has been identified in several minerals, including cerite, orthite, thertveitite, wolframite and euxenite (a niobate, tantalate and titanate of several rare elements in which scandium was originally discovered). It is a metal which tarnishes in air (shows a pink colouration), burns easily and reacts with water to produce hydrogen gas. Applications for scandium have not yet been fully investigated and its use is limited primarily to research.Foil - Thin sheets of pure metal and metal alloys. Due to their fragile nature, some foils are coated on one side with an acrylic or polyester support. Where foils are supported they are indicated in the detailed item description.
