  • Calcium carbonate | CaCO3 - PubChem

    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.

  • 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 eggshells, snail shells, seashells and pearls. 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.

  • Calcium Carbonate - an overview | ScienceDirect Topics

    Calcium carbonates are one of the most abundant minerals in the earth's crust. They occur in the form of limestone and chalk, formed from fossils, and marble, formed from the metamorphosis of sedimentary rock. They consist mostly (>98%) of calcium carbonate (CaCO 3), with trace amounts of magnesium carbonate, iron oxide, and aluminum silicates. Dolomite is a blend of

    Le carbonate de calcium est un minéral polyvalent et essentiel qui se trouve dans notre vie quotidienne. ORIGINES Le carbonate de calcium fait partie des minéraux les plus abondants sur Terre et représente environ 4 % de la croûte terrestre. Il est présent naturellement dans trois principaux types de roches : la craie, le calcaire et le marbre.

  • What is a coral reef made of? - National Ocean Service

    Massive reef structures are formed when each individual stony coral organism—or polyp—secretes a skeleton of calcium carbonate. Most stony corals have very small polyps, averaging one to three millimeters (0.04 to 0.12 inches) in diameter, but entire colonies can grow very large and weigh several tons. These colonies consist of millions of polyps that grow on
