Calcium Carbonate - an overview | ScienceDirect Topics

The solubility of calcium carbonate in water is very low, e.g., below 1 gram per litre at 20 °C under 1 atmosphere CO 2 pressure. Its solubility is strongly influenced by partial pressure of CO 2, temperature, and concentration of other salts in solution.Changes in super saturation and hence precipitation and scaling usually occur as a result of temperature increase or pressure decrease ...

Lime (material) - Wikipedia

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.
