Calcium carbonate has established itself as the main extender in paints and coatings, but should be considered as a functional filler rather than an extender due to   Particle shape can influence the shade of a pigment and properties of the paint.

Particle Size Pigment particles are not usually spherical. They can have different dimensions depending on whether one measures the length, width or height. Particle size is an average diameter of primary particles. Typical ranges are: Carbon black - to µm; For precipitated calcium carbonate (PCC), it is well known that the degree of structuring has a strong influence on the performance of the pigment as a paper :// The beginnings: Calcium carbonate in glazing putty and rubber by Johannes Rohleder 1.
