It is clearly evident that numerous mineralogies are utilised for paper filling applications however, these minerals are all classified in much the same way. Particle size and size distribution, pigment brightness, refractive index, particle shape, and specific surface area are quantifiable characteristics that can be used to predict how the pigment will perform in various paper applications. To a lesser degree, particle charge, or zeta potential, plays a role in how the filler interacts with various paper chemical additives and influences the manner in which the mineral is retained in the paper web. 

With titanium dioxide, the development of opacity and tinting strength depends on light-scattering power, which is governed by refractive index, particle size distribution, Ti02 content, and dispersion in the polymer. 

In reflection of radiation at solid matte surfaces, diffuse and specularly reflected energies are superimposed. The intensity of the diffusely reflected energy is dependent on the angles of incidence and observation, but also on the sample packing density, sample crystalline structure, refractive index, particle size distribution, and absorptive qualities. Thus, an ideal diffusely reflecting surface can only be approximated in practice, even with the finest possible grinding of the samples. There are always...
