The Element Cadmium


This is one of the elements known for causing cancers and found in zinc ores. Therefore, Cadmium is isolated during the production of zinc. About 75% of world’s Cadmium is used for batteries and the most of the remaining 25% is used for pigments, coating and plating, and as stabilizers for plastic. Cadmium is also used as a barrier to control nuclear fusion. Using for paint pigments, television tubes, semiconductor production, as a PVC stabilizer are some of the other uses of Cadmium.

China is the current top producer of Cadmium producing one sixth of the world’s demand followed by South Korea and Japan. Usually Cadmium is rare and occurs in small quantities.
