Calcium carbonate is an inorganic chemical compound with the chemical formula CaCO3. Calcium carbonate is one of the most popular chemicals which is first encountered in school classrooms, where the use of chalk (a form of CaCO3) is found. It is found in the earthâ??s crust. It is also found in many forms such as marble, limestone, etc. Although they are available in various forms they are chemically similar and only differ physically. They are also referred to as calcite. Calcium carbonate is a non-toxic and odourless compound commonly found as a white mineral which occurs naturally in chalks, limestones and marbles. 1. Ground Calcium Carbonate â?? Produced via extraction and processing of naturally occurring deposits. GCC crystal shape is irregularly rhombohedral and has a broader size distribution. 2. Precipitated Calcium Carbonate â?? Produced via chemical precipitation via a carbocation process or as a by-product of some bulk chemical processes. PCC crystal shape depends on the product and the product and the particles are more uniform and regular with a narrow size distribution. 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 â?? and due to its special white color - as a coating pigment. Lauded among many industries for its use, calcium carbonate is a key player in the following industries: Healthcare. Oil. Plastic/Rubber. Cement. Glass. Steel. Paper. Construction.

Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different (and tailorable) handling properties. CAMEO Chemicals Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis. (NCI04) NCI Thesaurus (NCIt) Calcium carbonate is a calcium salt with formula CCaO3. It has a role as an antacid, a food colouring, a food firming agent and a fertilizer. It is a calcium salt, a carbonate salt and a one-carbon compound.

Calcium carbonate is a chemical compound of formula CaCO3, in white powder form. Calcium carbonate is practically undissolved in water (only 1.4 mg per 100 ml of water). But if the water contains carbon dioxide, the dissolution of calcium carbonate in the water increases due to the formation of bicarbonate.Calcium carbonate is rapidly degraded due to the effect of acids on it, as it liberates carbon dioxide.

Uncoated Calcium Carbonate CaCO3 â?? is synthetic calcium carbonate. It is white ultra fine crystalline powder having consistent Particle Size Distribution and Excellent dispersibility. The particle size, as well as the crystal form, is controlled by temperature, concentration of reactants and time.
Precipitated calcium carbonate, or PCC, is a synthetic calcium carbonate product. It is derived from, and possesses, the same chemical formula (CaCO3) as natural calcium carbonate (limestone), but is chemically purer than natural limestone.
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

Ground calcium carbonate (GCC) is commonly used in a number of paint and coating applications. It is used as an extender, an agent to either reduce or enhance gloss, an extender / spacer for titanium dioxide, a rheology modifier and as a paint and coating additive to densify the product. Calcium Carbonate is available in particle sizes ranging from D50 3.0 Microns to large white decorative chips. Calcium Carbonate is a relatively soft, insoluble mineral that is widely used to reduce cost and to control shrinkage in adhesive formulations. We provide Calcium Carbonate Powder in the widest variety of particle-size distributions. In high-end formulations, Our Calcium Carbonate helps the product maintain its viscosity, physical strength and properties. In commodity formulations, it can replace other more-expensive ingredients, improve gap-filling properties and modify viscosity. Features: Calcium Carbonate (CaCO3) powder used in Paints and Coatings has a spatial steric effect. The addition of calcium carbonate to paint can cause the relatively dense lithopone to stay in suspension and not sink to the bottom. It can increase the whiteness and luster of the paint film without reducing covering ability. It can prevent settling in latex paints, and can reduce the amount of dispersant needed. The use of calcium carbonate that has been activated by treatment with a chelated paint dispersion and coupling agent can significantly increase the paint's color intensity and reflection, and thereby enhance the luster, and also improve covering ability, abrasion resistance, adhesion, impact resistance, and flexibility. Calcium carbonate is used even more extensively in the aqueous paint industry. It can prevent pigment settling, promote good dispersion, and improve luster. Typically, 20%-60% calcium carbonate is used in aqueous paints. Calcium carbonate is also widely used with very high dosage (up to 60%) in Skim coat, Wall Plaster Powder, Putty as a filling material & whiteness improver.
