Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which contains both of those minerals). Calcium carbonate is a white, odorless powder or colorless crystals. Practically insoluble in water. Calcium carbonate is one of the most widely used minerals today.\u00a0 It has many uses in a wide variety of industrial and commercial applications.<\/p>\n

Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler \u2013 and due to its special white color \u2013 as a coating pigment.\u00a0 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.\u00a0 Filler is used at the wet-end of paper making machines, and calcium carbonate filler allows for the paper to be bright and smooth.\u00a0 As an extender, calcium carbonate can represent as much as 30% by weight in paints.\u00a0 Calcium carbonate also is used widely as a filler in adhesives, and sealants.<\/p>\n

Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets.\u00a0 It also is found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine.\u00a0 Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed.\u00a0 Calcium carbonate also benefits the environment through water and waste treatment.<\/p>\n

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.\u00a0 It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles.\u00a0 Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper.\u00a0 Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water.<\/p>\n
