Calcium Carbonate Pharmaceutical Use

Carbonate Carbonate in Pharmaceutical Industry

Pharmaceutical Industries use Precipitated Calcium Carbonate in the fermentation process and to manufacture tapped density tablet making.

Pharmaceutical Grade Precipitated Calcium Carbonate contains high content of CaCO3 and very low impurities like Pb, As, Hg, Fe etc. It is used to neutralize the acids in fermentation process and for calcium supplement tablets. Granulated Precipitated Calcium Carbonate makes it easier to shape calcium tablets.
