Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.
Ground calcium carbonate (limestone) is one of the most widely used filler materials having a blocky shape. Fig. 1. Particle shape, a critical attribute of papermaking fillers. Figure 2 illustrates a few of the particle shapes that are characteristic of different types of precipitated calcium carbonate (PCC) fillers (Gill 1989).
