Calcium carbonate is a substance with the chemical formula CaCO3. Calcium carbonate is an exceptional mineral that makes up more than 4% of the Earth's crust and is found all over the world. Calcium carbonate is one of the most widely used materials known to man. This substance can be produced artificially, and it is also found in eggshells and the membranes of animals such as snails and crabs. Pearls are also made of calcium carbonate.

Pearls are also made of calcium carbonate.

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

Applications of Calcium Carbonate:

Calcium carbonate turns into lime by losing CO2 when heated, which is used in construction work, in the iron extraction and steel production industry as a flux, and for the preparation of calcium carbide. Lime is also used in agriculture to improve the soil and adjust its PH.

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

Calcium carbonate is one of the most widely used minerals 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 papermaking industry, it is valued all over the world for its high brightness and light scattering and is used as an inexpensive filler to brighten the dull surface of paper..

Application of calcium carbonate in construction:

Calcium carbonate in construction is important and necessary for both making materials and as components and particles of cement. It is also used in making mortar for arranging bricks on top of each other, concrete blocks, stones, roofing, resin composition, and tiles. Calcium carbonate decomposes carbon dioxide and lime to create a basic material in the manufacture of steel, glass, and paper.

Calcium carbonate is used in the detergent industries, calcium carbonate in masterbatch industries, calcium carbonate in the enamel industries, calcium carbonate in the kenitex industries, calcium carbonate in the profile industries, and calcium carbonate in the glazing and ceramic tile industries..

Application of Calcium Carbonate in the Plastic and Rubber Industry:
Calcium carbonate is widely used in the plastics and rubber industries due to its low oil absorption, rapid dispersion, low cost, good gloss, and low hardness..

Application of Calcium Carbonate in the Paint Industry:
Calcium carbonate has a high consumption in the paint industry due to its reasonable price, optical and mechanical properties. The softer the calcium carbonate, the better the coating it gives to the paint..

Application of Calcium Carbonate in the Pharmaceutical Industry:

Calcium carbonate is almost insoluble in ordinary water and dissolves slowly in water that contains some carbon dioxide or has a high concentration of ammonium salts. It is almost insoluble in alcohol and boils in acetic acid, hydrochloric acid, and nitric acid..

Application of Calcium Carbonate as a Filler:

Calcium carbonate is used as a filler in industries. Fillers are added to liquids and solids to make one or more changes, such as increasing mechanical strength and formability, decreasing or increasing specific gravity, increasing heat resistance, changing concentration, and reducing the total cost.
Calcium carbonate in the paint and wood adhesive production industries, calcium carbonate in the plastics industries, calcium carbonate in the rubber industries, calcium carbonate in the flooring industries, calcium carbonate in the PVC sheet industries, calcium carbonate in the adhesive and resin industries, wire and cable, calcium carbonate in the PVC pipe industries, calcium carbonate in the artificial leather, ink, paper, pharmaceutical industries, the most application of calcium carbonate is in the paper industries, calcium carbonate in the plastics industries, and calcium carbonate in the paint manufacturing industries. Paper is formed from a cellulose network, whose fibers are filled with fine-grained mineral particles; coating materials are used to increase the print quality on paper in papermaking, and calcium carbonate can make up 5-50% of it..

Calcium carbonate can act as a pigment and reduce the need for polymer, accounting for 35% of the composition..
