Description

Cadmium metal ingots refer to the solid blocks or bars of pure cadmium that are produced during the refining and purification process. These ingots are typically obtained by melting and solidifying cadmium obtained from its ore or recycled sources.

Cadmium and its compounds have historically found applications in several industries, although their usage has been reduced due to environmental and health concerns. Here are some notable applications of cadmium:

1. Batteries: Cadmium was commonly used in rechargeable nickel-cadmium (NiCd) batteries due to its high energy density and long cycle life. However, its use has declined due to environmental concerns, and alternative battery technologies have gained popularity.
2. Coatings: Cadmium plating provides excellent corrosion resistance, especially in marine environments. It has been used to protect steel structures, aerospace components, and electrical connectors. However, its use has decreased due to the toxicity of cadmium and the development of safer alternatives.
3. Pigments: Cadmium-based pigments, such as cadmium yellow, orange, and red, have been widely used in the art and paint industry. These pigments offer high color intensity, stability, and lightfastness. However, their usage has decreased due to the potential health risks associated with cadmium exposure.
4. Solar cells: Cadmium telluride (CdTe) is a compound used in thin-film solar cells. CdTe-based solar cells have become increasingly popular due to their cost-effectiveness and high efficiency.
