Calcination is the thermal decomposition of limestone, primarily composed of calcium carbonate (CaCO3), into calcium oxide (CaO), commonly known as quicklime. The reaction is achieved by heating limestone at temperatures exceeding 825°C (1517°F), driving off carbon dioxide (CO2) and leaving behind calcium oxide.
