Calcium Carbonate
8.5 Calcium carbonate. Calcium carbonate is found in three forms: calcite, aragonite, and the very rare vaterite. Calcite is the most stable polymorph with hexagonal structure, and can have a great variety of particle morphologies. Aragonite, which evolves spontaneously to calcite, is orthorhombic.
13.1.1 Carbonates | CIE IGCSE Chemistry Revision Notes 2022
Limestone (calcium carbonate) is used in the manufacture of iron and cement. In the production of iron, limestone is added to the blast furnace where it decomposes to form lime (CaO) and carbon dioxide. The CO 2 produced is reduced to carbon monoxide, CO, by coke (almost pure carbon) where it acts as a reducing agent transforming iron ore into ...
