Calcium carbonate

Calcium carbonate is a mineral substance with the formula CaCO3, which is one of the most widely used substances known to mankind, this substance can be produced artificially, and of course, it is also present in eggshells and the membranes of animals such as snails and crabs. Pearls are also made of calcium carbonate.

Applications of calcium carbonate:

Calcium carbonate is extracted from the mine for industrial use. Pure calcium carbonate can be produced from marble or it can be formed by passing carbon dioxide through a calcium hydroxide solution.


Calcium carbonate is converted into lime by heat with the loss of CO2, which is used in construction works, in the iron mining industry and steel production as a smelting aid and for the preparation of calcium carbide. Lime is also used in agriculture to improve soil and adjust its pH.

Calcium carbonate is used in tile and ceramic industries, especially in the glazing industry. Due to the eutectic formation, it lowers the melting point of the set and when used in glaze, it lowers the thermal expansion coefficient of the glaze.

Calcium carbonate is one of the most widely used minerals, which is used in the paper, plastics, paints and coatings industries both as a filler and as a color coating (due to its special white color).

In the paper industry, it is valued all over the world for its high brightness and light scattering, and it is used as an inexpensive filler to brighten dull paper surfaces.
