Buying calcium carbonate is used in the plastic and rubber powder production industry as a filler and product resistance to heat and strength, and it also prevents plastic from softening and stretching. Calcium carbonate is the most important plastic filler, which increases thermal resistance, tensile strength, and hardness. The reason for using chemical powder with CaCO formula is a reasonable price, little oil absorption, ease of spreading, excellent shine, and softness. Also, calcium carbonate powder prevents polymer clumping and improves its dispersion. Calcium carbonate powder is used in this industry with the following characteristics: Cao content of at least %, Feo content of up to %, the moisture level of up to %, and meshes Consumption is more than .

The most common application of soil calcium carbonate and precipitated calcium carbonate is in the paper, plastic, and dyeing industries. The paper consists of a cellulose network, fibers filled with fine-grained mineral particles, and coating materials to increase printing quality. They are used in papermaking, where calcium carbonate can make up -%. Calcium carbonate can act as a pigment and reduce the need for polymer, so in PVC sheets, pipes, and windows, -% of the composition. In dyeing, -% of the volume of aqueous emulsions or solvents can include calcium to reduce the amount of TiO consumed

Other applications include micronized powder, printing compounds, glass making, sulfur generation from chimneys, welding and electrode industries, fire fighting (preparation of fire extinguishing powders), agriculture, leather making, water industry for water purification, sugar factories and Sugar, metallurgy, steel industries, pharmaceuticals, chemical industries as refractories, in food industries as acidity neutralizers and in gum production, for cloud production, in textile and clothing industries, sculpture, false ceiling, and MDF, machine carpet production, Macalleum, carpet, types of carpet glue and other industries.

Among the other benefits of buying calcium carbonate is that it speeds up blood coagulation and is used to prevent severe bleeding. In treating heart rhythm disorders, it is added orally as a supplement to the drugs related to heart failure. Calcium chloride is also used to treat the complications of diarrhea and vomiting. The aforementioned calcium compounds are widely used in veterinary medicine. This product is in the form of calcium carbonate compound powder, magnesium carbonate compound powder, and magnesium carbonate compound tablet. Also, alumina, magnesia and calcium carbonate suspension, alumina, magnesia and calcium carbonate tablets and calcium carbonate tablets are examples of other medicinal products with a chemical substance with the formula CaCO

Calcium carbonate powder is used as a filler in the paint industry. This powder is usually used with the following characteristics to make all kinds of colors in the paint industry: cao is more than %, Feo is less than %, and mesh is more than . Therefore, due to the high type of copper, the price of calcium carbonate for use in these industries is high. In the production of traffic paint, calcium carbonate with mesh is used. Sugar particles in the produced powder can be felt under the hand. This powder without black grains and a white hand and with high analysis is produced in Ara Sang Alvand company.
