Precipitated calcium carbonate is widely used as fillers, and finds uses in many products from asphalt to paper. The higher value, nano-grade PCC (top cut-off size 100 nm) is used as an efficient filler in the paper, pharmaceutical, paint, plastic, caulk and sealants industries.  Precipitated calcium carbonate fillers for papers Papers are generally made of cellulosic pulp fibers, a derivative of renewable natural bio-resources comprising wood and non-wood lignocellulosic constituents. In the production of paper grades such as papers ...  Read more 

Calcium carbonate (CaCO3) is widely found in almost all living creatures, as well in some human tissues. Compared with other inorganic materials, over the years, CaCO3 has shown auspicious potential for the development of smart carriers for various anti-malignant neoplastic drugs. It is biodegradable, biocompatible and also a good pH-sensitive material. These properties make CaCO3 suitable for controlled degradability both in vitro and in vivo. Precipitated calcium carbonate can be handily and flawlessly produced in a precipitation reaction by reacting ...  Read more 

​Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Limestone constitutes approximately 10 percent of the sedimentary rocks exposed on the earth’s surface. Either limestone or marble may be used as the basis for crushed or ground calcium carbonate. Ground calcium carbonate, commonly referred to as GCC, is widely used as an industrial mineral. Three primary attributes: particle size, color and chemical purity define the quality of the GCC, and define the suitability of use for any given ...  Read more
