Zinc carbonate

Other names: Zinc carbonate, smithsonite, calamite

Zinc carbonate, commonly known as Zinc carbonate, smithsonite or calamite, is a chemical compound with the formula ZnCO3. It is a mineral of the carbonate group that occurs naturally in the form of light green or blue-grey crystals. Smithsonite is named after the British scientist James Smithson, who made a significant contribution to the development of chemistry and mineralogy. His discovery enabled further scientific development and laid the basis for the widespread use of this carbonate in industry and the manufacture of various products.

Zinc carbonate has diverse applications. It is a key component of some pharmaceutical products and is commonly used as a dietary supplement for people who suffer from zinc deficiency in the body. It is additionally important for the proper functioning of the immune system. In the cosmetic industry, it is used in the manufacture of various cosmetic products, including makeup and creams, where it serves as a bleaching agent and UV filter. In the construction industry, this mineral is used in the production of cement, where it helps reduce the amount of harmful chromium. Another use is in the rubber industry, where it is used as a vulcanisation activator. Zinc carbonate is thus found in many products that we use every day, although we often do not realise it.
