Application

Cadmium carbonate serves a range of functions primarily in the industrial and chemical sectors. This naturally occurring mineral, available as a white powdery solid, is instrumental as a catalyst in organic synthesis. It acts as a key starting material for producing various cadmium salts and serves as a crucial raw material in the creation of pigments for ceramics and frits. Its utility extends further to the production of intermediates necessary for manufacturing polyester, glass pigment flux, and is also used in the development of organic catalysts and plastic stabilizers. Despite its limited commercial applications, its role is fundamental in these specific uses, emphasizing its significance in specialized chemical and manufacturing processes.
