| Legende |
| Herkunft des Namen: | latein: Scandia, Scandinavia |
| Beschreibung: | Fairly soft, silvery-white metal. Eighth most abundant 'rare earth' found in the earth's crust (5.0 ppm). |
| Entdeckt von: | Lars Nilson |
| Jahr: | 1879 |
| Ort: | Schweden |
| Quelle(n): | Occurs mainly in the minerals thortveitile (~34% scandium) and wiikite. Also in some tin and tungsten ores. Pure scandium is obtained as a by-product of uranium refining. |
| Verwendung(en): | Scandium metal is used in some aerospace applications. Scandum oxide (Sc2O3) is used in the manufacture of high-intensity electric lamps. Scandium iodide (ScI3) is used in lamps that produce light having a color closely matching natural sunlight. |
