  • Calcium carbonate Wikipedia

    Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium

  • Effect of calcium carbonate on low carbon steel corrosion

    30/12/2015· In addition, CaCO 3 also plays an important role on CO 2-corrosion of steel and it is very abundant in the fluids in case of carbonate reservoirs and also because the cement of the oil well structure reacts with dissolved CO 2 precipitating CaCO 3 in the porous of cement that further can be dissolved into the fluids , , . The last case can be particularly relevant on the well casing corrosion.

  • What is Calcium Carbonate? Industrial Minerals

    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. Calcium carbonate crystals are referred to as calcite. The calcite crystal generally is considered a rhombohedron because of its cleavage
