Calcium carbonate, or CaCO3, comprises more than 4% of the earths crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to man. Uses Paper, Plastics, Paints, and Coatings: Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler and due to its special white color - as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper. Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth. As an extender, calcium carbonate can represent as much as 30% by weight in paints. Calcium carbonate also is used widely as a filler in adhesives, and sealants. Personal Health and Food Production: Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It also is found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine. Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed. Calcium carbonate also benefits the environment through water and waste treatment. Building Materials and Construction: Calcium carbonate is critical to the construction industry, both as a building material in its own right (e.g. marble), and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water Element CaCo3 99.20 MgCo3 0.20 Fe2O3 0.01 HCI 0.20 Whiteness 96.30 Yellowness 0.70 Size : 20-8 Micron

1. CaCO Advantages in Paint and Surface Coatings: It solidifies It controls the viscosity It lowers the cost by reducing the consumption of titanium dioxide It enhances opacity due to its high whiteness property It strengthens It increases the impact resistance of the paint film It gives brightness to the paint It prevents the paint films to peel off It provides a smooth film surface It has an ultra-hiding power It has a high dispersion feature 2. CaCO Advantages in Plastic Sector: Some advantages of the calcite over the plastics are as follows: Depending on different chemical surface coating, it provides dop oil saving. It provides pigment saving due to its high whiteness. It has a flame retardant property due to its chemical structure. It increases the writability of the packing materials. It has a positive effect on notched impact strength. It has a regulatory impact on the viscosity in polymer. The micronized calcite used as a filling material in plastic sector: Must control the rheological properties of PVC plastisols, Must not include heavy metals causing polymers to age, Must have high chemical purity, Must have high whiteness for saving expensive white pigments, Ground particles must not gather together and agglomerate again, Must not intake high amount of oil, Must not absorb the flux oil or the chemical substances used in the formulation, Must not cause machines to be worn, Must have homogeneity, Must have a high rate of whiteness for saving expensive white pigments and dyeability at high filling levels, Must disperse easily, Must enhance hardening, the structural properties of the final product, impact resistance, stability and resistance against ageing, Must protect against heating up due to its solidifying effect, Must prevent blocking on broken film surfaces, Must be scentless, tasteless and non-toxic.
Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water. Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size. Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements
