Precipitated Calcium Carbonate

Precipitated Calcium Carbonate: 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 distribution.  PCC is available in numerous crystal morphologies and sizes, which can be tailored to optimize performance in a specific application.
