Precipitated calcium carbonate (PCC) is an innovative product derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or "milk-of-lime", with carbon dioxide. The resulting product is extremely white and typically has a uniform narrow particle size ...
