If the refractive index is lower than 1.7, they are classified as fillers (see Table 1). Refractive Index and Scattering Power To understand why titanium dioxide, especially the rutile form, offers such great advantages in hiding power, it is only necessary to compare the refractive index of rutile TiO 2 to the refractive indices of anatase TiO 2, other commercial white pigments, and polymer systems as shown in Table 1. Because of very high refractive index, TiO2 has been widely used as a white pigment. Moreover, (3) c = f 0, v = f , where, 0 and are the associated wavelengths for c and v, and f is the corresponding frequency. 99.9.
