Abstract: The effect of salt milling process on the crystal size, morphology, and color characteristics of C.I.
Pigment Red 57:1 was studied. The primitive morphology and color properties of the pigment after synthesis were
studied in the former series work. The size and morphology of primary particles and the second aggregation
features should be considered because they are very important to determine pigment quality. We compared the
primary morphology of pigment particles before drying with the secondary aggregated morphology of pigment
particles after drying and salt milling process. Morphological properties were investigated by particle size analysis,
X-ray diffraction, and scanning electron microscopy and color measurement was carried out. Significant reduction in
particle size as well as enhanced crystallite size after salt milling process was observed. This result might give a
difference in color of the pigment, turning into brighter and more blue-toned red color. It was revealed that
synthesis condition affect the morphology and color of the pigment even after milling. Increase in HCl
concentration in the synthesis process enhanced crystal size and quality forming bluer-red pigments but an increase
in CaCl2 concentration resulted in more amorphous crystals forming darker-red pigments after salt milling. |
