Calcium carbonate Essential Chemical Industry

Very fine and pure calcium carbonate is used as filler in plastics and paper. A filler is a substance that gives bulk but does not alter the properties of the substance to which it is added and is also inert. Calcium carbonate when very finely crushed (less than 2 microns) is used in paints to give a 'matt' finish. Figure 8 Uses of limestone.
