On this page I'll provide comprehensive data for Cadmium. I hope you profit from it.
Cadmium Overview
Name Origin
Greek: kadmeia (ancient name for calamine (zinc oxide)).
Symbol
Cd (Cadmium)Description
Soft, malleable, blue-white metal.
Discovery
Discovered By: Fredrich Stromeyer
Year: 1817
Location: Germany
Sources
Obtained as a by product of zinc refining.
Uses
Used in nickel-cadmium batteries. Also in electroplating steel and in the manufacture of berings. Its compounds are found in paint pigments and a wide variety of intense colors. Boiling cadmium gives off a weird, yellow-colored vapor that is poisonous.
