Calcium carbonate is an inorganic compound, the chemical formula is CaCO3, is the main component of limestone, marble, etc. Calcium carbonate is usually a white crystal, odorless, basically insoluble in water, and easily reacts with acid to release carbon dioxide [1]. It is one of the common substances on the earth, present in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.
The main component of limestone is calcium carbonate CaCO3, while the main component of quick lime is CaO. The quick lime reacts with water to form calcium hydroxide Ca(OH)2, commonly known as hydrated lime. All natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomitic limestone, etc., can be used to produce lime. In coastal areas, shells are used as raw materials, fired into shell ash, and used as quicklime.
Lime and limestone are used in large quantities as building materials and are important raw materials for many industries. Limestone can be processed directly into stone and fired into quicklime. Lime is quick lime and hydrated lime. The main component of lime is CaO, which is generally blocky, pure white, and light gray or light yellow when containing impurities. Quicklime absorbs moisture or adds water to become slaked lime, slaked lime is also called hydrated lime, its main component is Ca(OH)2.
