The abrasive wear of calcium carbonate, on melt processing equipment, is not considered significant but increases with increasing levels. Calcium carbonate nanoparticles are commercially available and are claimed to give a cost-effective way of increasing impact strength; their use in impact modified PVC has improved mechanical properties.

Calcium carbonate scale on a piece of pipe. Excessively hard water will nearly always have to be softened in order to protect the water treatment plant equipment and piping systems. At a hardness of greater than 300 mg/L as calcium carbonate, scale will form on pipes as calcium carbonate precipitates out of the water.

This invention concerns a process and equipment for producing precipitated calcium carbonate. According to the process, limestone is burnt at a high temperature to form calcium oxide and, thereafter, calcium carbonate is formed from calcium oxide in the presence of water and carbonate ions and the formed calcium carbonate is recovered.

Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate. This experiment can be carried out conveniently
