Application

Cadmium is a versatile metal known for its unique properties and applications across various industries. It is characterized by its silvery-white appearance with a bluish tinge, its high ductility, and its malleable nature, making it easy to work with. Primarily produced as a by-product from the extraction, smelting, and refining of non-ferrous metals like zinc, lead, and copper, cadmium finds its use in numerous fields due to its ability to resist corrosion and form strong alloys. It is widely utilized in the production of nickel-cadmium batteries, providing reliable and efficient energy storage. Cadmium is also employed in electroplating, offering a corrosion-resistant coating that is notably effective, even in thin layers. In addition, cadmium compounds serve as pigments, stabilizers, and coatings, as well as in electronic components. Despite its beneficial uses, cadmium and its compounds are known for their toxicity, and handling them requires careful safety measures to avoid exposure.
