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 well established as a filler and coating pigment for premium quality paper products.  PCC enhances optical properties and print characteristics of paper products, improves paper machine productivity, and can reduce papermaking costs through the replacement of more expensive pulp fiber and optical brightening agents.  PCC is often used in calcium-based antacid tablets and liquids.  Being high in calcium content, PCC enables the formulation of high dosage calcium supplements and multi-vitamin/mineral tablets.  The small particle sizes and special particle shapes contribute to the development of good tasting calcium fortified foods and beverages.
