Calcium Carbonate Description

Calcium carbonate (CaCo3) is available in nature in limestone or calcite forms and in different colors from white up to gray.It is one of the most common filling materials in different industries like Paint industries, Plastic, Granule P.V.C., Wire & Cable, Enamel, Paper, Adhesive and Resin and Chemical Industries.

Calcium carbonate is a chemical with the formula CaCO3 .It is a common substance found in rocks in all parts of the world (most notably as limestone), and is the main component of shells, snails, coal balls, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural, and is created when calcium ions in water react with carbonate ions creating lime scale. It is commonly used medicinally as calcium supplement or as an antacid, but excessive consumption can be hazardous. Calcium carbonate occurs in nature in one of three crystalline mineral forms – calcite, aragonite or vaterite and contains calcium atoms coordinated by 6 oxygen atoms, 

We manufacture two types of Calcium Carbonate, 
Calcium Carbonate Coated
Normal Calcium Carbonate (non-coated) 

Calcium Carbonate M and Calcium Carbonate C are generally used in fluid-Loss-Control situations re a larger particle size than Calcium Carbonate F. Calcium Carbonate can also be added on a periodic basis for seepage control to limit losses (Loss control and leak-off) to high-permeability formations. It is practically effective when drilling with high differential pressure caused by an overbalanced condition or when drilling depleted zones.
Custom manufacturer of calcium & calcium carbonate for a variety of applications. Calcium carbonate is suitable for use in the glass industry as additives used in the production of float & container glass, fillers for plasticized & rigid PVC, unsaturated polyesters, polypropylene, polyethylene, rubber, foamed carpet backings, asphalt, paints, coatings, sealants, adhesives & plastisol’s, extenders in paints & coatings, plastisol’s, caulks, adhesives, mastics, fiberglass reinforced polyester compounds, plaster of Paris, wall board, powder coatings, thermoset polyesters, acrylic & silicone based sealants & filled polyolefin compounds for flooring, cove base & other building products. Calcium carbonate is also suitable for use as fertilizer & for environmental protection applications such as flue gas desulphurization, drinking water treatment & waste water treatment and in drilling fluid additive agents Carbonates are excellent acid soluble weighting agent in drilling, drill‐in and workover/completion fluids.

Material Safety Data Sheet

Calcium carbonate


Chronic ingestion may cause hypercalcemia, alkalosis, and kidney damage. May also produce “milk-alkali syndrome” characterized by neurological symptoms such as irritability, lethargy, stupor, and coma.





Section 4 - First Aid Measures


Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until no evidence of chemical remains. Get medical aid at once.


Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops.

I ngestion:

Do not induce vomiting. If victim is conscious, give 2-4 glasses of water or milk. Get medical aid at once.

I nhalation:

Give artificial respiration if necessary. Move victim to fresh air. Keep victim warm and at rest. Get medical aid at once.

Notes to Physician:

Treat symptomatically and supportively.
