Lime, sometimes referred to as quicklime, is a term commonly applied to a number of related materials. Pure lime is calcium oxide (CaO) formed by "burning" a form of calcium carbonate such as limestone or marble (CaCO3). Dolomite, a calcium magnesium carbonate (CaMg (CO3)2) can also be calcined to form dolomitic lime, which has different ...
