| Legende |
| Herkunft des Namen: | Von der skandinavischen Gottheit, Vanadis |
| Beschreibung: | Soft, ductile, silvery-white metal. Resistant to corrosion by moisture, air and most acids and alkalis at room temperature. |
| Entdeckt von: | Nils Sefström |
| Jahr: | 1830 |
| Ort: | Schweden |
| Quelle(n): | Found in the minerals patronite (VS4), vanadinite [Pb5(VO4)3Cl], and carnotite [K2(UO2)2(VO4)2.3H2O]. Pure metal produced by heating with C and Cl to produce VCl3 which is heated with Mg in Ar atmosphere. |
| Verwendung(en): | It is mixed with other metals to make very strong and durable alloys. Vanadium pentoxide (V2O5) is used as a catalyst, dye and color-fixer. |
