Ground Calcium Carbonate
Ground calcium carbonate is a white or slightly yellow crystalline compound that occurs naturally as an ingredient in soil and rocks. Calcium carbonate helps to bind water, nutrients, and other materials together so they can be transported through the soil more easily. It also forms the base of many plant roots. It is a type of talc that is made from crushed limestone. The chemical formula for GCC is CaCO3. The term ‘GCC’ refers to a calcium carbonate that has been ground into particles. This type of calcium carbonate is found in the form of limestone, marble, or chalk and can be used as an additive in food products as a supplement to provide dietary calcium. Mewar Micron is a well-known Ground Calcium Carbonate Supplier in India. Calcium carbonate is an important industrial chemical and is used in a wide range of industries including construction, paper, and textile industries. It is also produced by marine and terrestrial animals. For example, corals secrete calcium carbonate to form the hard invertebrate’s exoskeleton.

Precipitated calcium carbonate
Precipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions. Normally, a filtered solution of calcium hydroxide Ca(OH)2 (from burnt lime) is used as the calcium source. This must not contain any colored impurities. Calcium carbonate is precipitated by the admixture of gaseous carbon dioxide or sodium carbonate Na2CO3.
The form of calcium carbonate obtained – in other words, its particle shape and particle size distribution – depends on the precipitation conditions, such as concentration, temperature and temperature change during precipitation, agitation energy, pH and other factors.

Coated Calcium Carbonate
Coated Calcium Carbonate is same as calcium carbonate with a thin layer of stearic acid which will provide these features High hydrophobic effect -To get easy and homogenious dispersion -Low oil, DOP, and polymer absorption Increase chemical and mechanical strength -Togethigh quality surface and brightness It is applied in paint industry, rubber, plastic, UPVC windows and frames.Precipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions.
