Legende

Herkunft des Namen:	latein: indicum (die Farbe Indigo), Farbe die man im Spektroskop sieht.
Beschreibung:	Rare, very soft, silver-white metal
Entdeckt von:	Ferdinand Reich, T. Richter
Jahr:	1863
Ort:	Deutschland
Quelle(n):	Found in certain zinc ores.
Verwendung(en):	Used to coat high speed bearings and as an alloy that lowers the melting point of other metals. Relativly small amounts are used in dental items and in electronic semiconductors.
