Calcium Carbonate
Calcium Carbonate Manufactures in India
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.

Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. The primary type of industrial product is ground calcium carbonate, or GCC. GCC, as the name implies, involves crushing and processing limestone to create a powdery-like form graded by size and other properties for many different industrial and pharmaceutical applications.As interesting as calcium carbonate may be in nature, its impact and value to our everyday life are truly extraordinary.
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.
Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. 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.
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. Our High end Imported Microniser ensures the highest grade & uniform particle size product for the industries like Plastic & paints.

Precipitated Calcium Carbonate Manufactures
PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate.
What Is Unique About A Precipitated Calcium Carbonate?
The different shapes allow PCC to act as a functional additive in sealants, adhesives, plastics, rubber, inks, paper, pharmaceuticals, nutritional supplements and many other demanding applications.
In the PCC process, products can be made with very small sizes, with high surface areas, high oil absorptions, and/or with different powder bulk densities— from ultra-low to super-high powder densities. Precipitate Calcium carbonate is manufactured by calcinations of selected best quality limestone with hightest percentage of calcium carbonate with low magnesia, Silica, Iron & other natural impurities. Oxide so obtained is slacked to produce lime solution and further carbonated into precipitated calcium carbonate in controlled conditions.
PCC is widely used in industries like
- Paper : PCC is perfect for filling papers where maximum light scattering (opacity and brightness) and bulk are desired. It is ideal for improving machine runnabilty and sheet closure while enhancing scattering with reduced strength loss. This product provides superior stiffness and strength, enhances coated papers where higher brightness and gloss is desired, optimizes the printing performance of coated papers by providing smooth and opaque surfaces for clear, sharp color printing.
- Adhesives & Sealants : PCC as a rheological additive provides viscosity, thixotropy, shear thinning, and yield value for economical control of slump, sag, and extrusion or spray-application rates.
- Paint and Coatings : It is most commonly used in paint as an extender for titanium dioxide, or TiO2. The small and narrowly distributed PCC particles help space the individual TiO2 particles and maximize their hiding power. This extension of the prime white pigment can improve opacity and reduce cost.
- Pharmaceuticals : In pharmaceutical applications, the most common use of calcium carbonate is the active ingredient in calcium-based antacids. Calcium carbonate is a rapid and effective acid neutralizer that is also economical to use. During fermentation of antibiotics, precipitated calcium carbonate is added to help control and buffer the pH of the broth. When fermentation is complete, PCC is added as a flocculent, to help clarification and filtration. A high surface area grade is normally used to provide the maximum area for absorption and for rapid reaction.
- Plastics : Precipitated Calcium Carbonate (PCC) products including ultrafine particles in the nano rang which are highly functional additives that provide superior impact strength in rigid or unplasticized PVC resin systems. Their uses include window profiles, fencing, siding, thermoforming, calendared stock and foamed PVC. They are also useful as thickening and gloss-producing minerals in unsaturated polyesters.
