Particle structures of Inorganic (Cr, Fe)2O3 pigment changed in different grinding methods. • Changing particle structures affected the reflection angles and hue of light in the visible region. • Milling methods damaged the bond formed after calcination. • Pigment XRD peak intensities were higher when ground with jet-mill. •
Inorganic pigments are insoluble in the surrounding medium and their optical effect arises from selective light absorption. They are classified according to their color, origin, method of production, and the character of the pigment material. Inorganic pigment technology is directly related to the development of new synthesis methods and the
