About Scandium

Scandium is a rare metal known also as a transition metal. In its pure form, this metal is quite soft and reactive, especially with water and air. It is a carcinogen and quite a toxic element. Its name is derived from a Latin word meaning Scandinavia. Scandium is rather used for research since it is very rare and can be found only is a few rare types of minerals. As a metal, scandium has very low density, so it is used in alloys with other light metals like aluminum in aircraft industry, etc. Combined with mercury and iodine, scandium is used for producing bulbs.
