Uses

 

 

The material is processed through naturally occurring sea shells of Oyster Origin. Unlike other grades which are inorganic in nature. Material derived from Oyster shells is considered to be derived from Organic Source. Oyster Shell Calcium Carbonate is in its purest form with 99.7 % assay as CaCO3. The material is creamiest in color owing bulk density between 0.6 to 0.8 gms/cc. Its major market is in the pharmaceutical segment due to non toxic and relatively high CaCO3 contents.
