CHEMICAL FORMULA CaCO3

WHAT IS CALCIUM CARBONATE?


Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s 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. 

APPLICATION

LDPE master batches
Rigid PVC Pipes
Leather Cloth Industry
Rubber Industry
As a flux in Glass Industry & in sizing of Textile goods
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. 
Used as an inexpensive filler to make bright opaque paper. 
calcium carbonate can represent as much as 30% by weight in paints. 
Used widely as a filler in adhesives, and sealants.
Dietary calcium supplement,
Antacid,
Phosphate binder,
As base material for medicinal tablets. 
Used in toothpaste,
As active ingredient in animal feed. 
Calcium carbonate also benefits the environment through water and waste
As a food additive
As anticaking agent,
Used as a firming agent in many canned or bottled vegetable products.
In ceramics/glazing applications
Ground calcium carbonate is an abrasive (both as scouring powder and as an ingredient of household scouring creams), i
A paste made from calcium carbonate and deionized water can be used to clean tarnish on silver.[15]
Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace.
Is added to drilling fluids as a formation-bridging and filtercake-sealing agent;
Is used to increases the density of drilling fluids to control the downhole pressure.
Is an essential ingredient in the microporous film used in babies' diapers and some building films as the pores are nucleated around the
In Polypropylene compounds to increase rigidity, for use in high temperatures.
 Rubber products: Hardness / tenacity /strength (tensile, tearing & impact) / processing capability
