Herkunft des Namen:
Beschreibung:	Hard, steel-gray to white metal. Highest melting point of all metals.
Entdeckt von:	Fausto and Juan José de Elhuyar
Jahr:	1783
Ort:	Spanien
Quelle(n):	Occurs in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
Verwendung(en):	Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives.
