Legende

Herkunft des Namen:	spanisch:
Beschreibung:	Rare, very heavy, soft, silvery-white metal.
Entdeckt von:	Julius Scaliger
Jahr:	1735
Ort:	Italien
Quelle(n):	Produced from deposits of native, or elemental, platinum.
Verwendung(en):	Used in jewelry, to make crucible and special containers and as a catalyst. Used with cobalt to produce very strong magnets. Also to make standard weights and measures. Resists corrosion and acid attacks except aqua regia.
