The main applications of microcalcite are: 1. Plastic and polymer production: microcalcite is used as a composite filler to improve the physical and mechanical properties of plastic products, such as strength and rigidity. 2. Paint and coating production: microcalcite is used to improve the optical properties of paints, as well as to increase their durability and rheological characteristics. 3. Rubber production: microcalcite is added to rubber compounds to improve their mechanical properties, such as strength and wear resistance. 4. Construction industry: microcalcite is used in the production of building materials such as plaster, gypsum board panels, ceramic tiles, etc. 5. Paper production: microcalcite is added to the paper production process to improve printing quality, increase the brightness and whiteness of paper. 6. Food industry: microcalcite is used as a food additive (E170) to regulate acidity and improve the texture of food products. 7. Agriculture: microcalcite is used as a fertilizer to correct soil acidity and enrich it with calcium. 8. Pharmaceutical industry: microcalcite is used in the production of drugs as a filler, stabilizer and pH regulator. 9. Cosmetics industry: microcalcite is used in cosmetic products such as creams and powders to improve their texture and coating properties. 10. Electronics production: microcalcite is used in the production of electronic components and devices as a dielectric material. 11. Oil and gas industry used as a weighting agent in the production of drilling mud and other process fluids. 12. Production of dry building mixtures dry multicomponent plasters, putties, putties and grouts, decorative building mixtures, whitening and coloring compounds.
