Pokraskin A large number of CICPs contain transition metal oxides without a significant amount of a colorless base oxide. These pigments, listed in Table 5.3, employ either green chromium(III) oxide, red iron(III) oxide, or a combination of the two as a base. They are thus referred to as chromites or ferrites [7], for the chromium and iron bases, respectively. Most adopt the spinel configuration, with the other important structures being those of corundum and hematite.
Chromite and ferrite pigments have physical properties similar to those of the titanates and aluminates. Nearly all pigments of this variety are of brown and black shades, with just a few greens and green-blues. Some have unique infrared spectral properties that make them of interest in addition to their durability and color stability.
