Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells.
The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (e.g. for food or pharmaceutical use), can be produced from a pure quarried source (usually marble).
Alternatively, calcium carbonate is prepared by calcining crude calcium oxide. Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate.
- CaCO3 → CaO + CO2CaO + H2O → Ca(OH)2Ca(OH)2 + CO2 → CaCO3 + H2O
- Formula: CaCO3 Molar mass: 100.0869 g/mol Density: 2.71 g/cm³ IUPAC ID: Calcium carbonate Melting point: 825° C
