Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 ...

Cadmium Plating | Cadmium Corrosion Resistance
Cadmium provides tough corrosion resistance in part because the finish is "sacial." That is, cadmium "saces" itself to protect the metal it covers. In the face of corrosive substances, the cadmium coating will corrode before the steel or other material it is covering. Many times it provides the corrosion protection of a common (but ...

Cadmium - Wikipedia
Cadmium is a rare element, not found in its pure state in nature. It occurs mainly as cadmium sulfide (CdS, or greenockite) in zinc de-posits. Cadmium is chiefly recovered as a by-product of zinc concen-trates, and its production depends on the demand for zinc (Llewellyn 1994). The United States began commercial production of cadmium

Cadmium - an overview | ScienceDirect Topics
In moist air, zinc becomes covered with a grayish coating of basic carbonate, Zn 2 (OH) 2 CO 3, which protects it from further attack by the atmosphere. Cadmium tarnishes only slightly, also forming a basic carbonate. Zinc is hard and brittle, and becomes malleable and ductile at 150°C, while cadmium is soft enough to be cut with a knife.

The original cadmium is a rare soft metal, similar to zinc but much harder to find naturally in the earth. It was only when it was discovered as a by-product of the zinc refining process that it became used a commercial pigment. This discovery took place in 1817, when the German chemist Friedrich Stromeyer was inspecting pharmacies.

Cadmium is an element. Its most abundant naturally-occurring isotope is non-radioactive. It is found in nature in mineral forms and is obtained for commercial uses principally from cadmium ore, called greenockite, which is commonly found in association with zinc ore. Commercial production of cadmium ore depends on the mining of zinc (ATSDR 1999).
