Zinccar bonate; Zinc monocarbonate; Zincspar; Carbonic acid, zinc salt (1:1)
Description
Zinc carbonate appears as a white, fine amorphous powder, odorless, tasteless and with a fine texture. It is stable at room temperature, insoluble in water and alcohol, dissolves rapidly in acids with the release of carbon dioxide gas, and decomposes into zinc oxide and carbon dioxide when heated at high temperature. As an inorganic carbonate, it is usually synthetic in industry, and its natural form is smithsonite.
