Calcium Carbonate,Natural Calcium Carbonate,Precipitated Calcium Carbonate,Activated Calcium Carbonate,India

We offer calcium carbonate, which is one of the most useful and versatile materials known to man. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. Calcium carbonate, or CaCO₃, comprises more than 4% of the earth’s crust and is found throughout the world.

The 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. In industry Calcium Carbonate is also known as calcium carbonate, filter, chalk.

We offer natural calcium carbonate that results directly from the exploitation of pure carbonate ore bodies. We maintains the carbonate very close to its original state, ending up in a finely ground product delivered either in dry or slurry form. We have developed a high level of know-how which ensures the highest standards of purity and consistency in the material produced. Our natural calcium carbonate is delivered to a wide range of manufacturing industries, for the finest grades.

Our coated calcium carbonate has a stearic acid coating that makes the hydrophilic surface of the calcium carbonate less hydrophilic. This coating on calcium carbonate improves dispersion of the its particles into the polymer melt.

It is a super ultra fine and very narrow particle size distribution precipitated calcium carbonate specially formulated as functional filler and extender in rubber products.It is widely used in various industries as filter or extender, thus assumes crucial importance in chemical and allied industries. PVC, Rubber, are some of the calcium carbonate using industries.
