          Abstract

          The α-Fe 2O 3@SiO 2 reddish pigments with core–shell structure were successfully prepared by hydrothermal and Stöber methods. The structure, morphology, and chromaticity of the synthesized pigments were characterized by XRD, SEM, TEM, FTIR, XPS, and colorimetry. The results indicated that the as-prepared pigments have the characteristics of narrow particle size distribution, high dispersion, and good sphericity. The α-Fe 2O 3@SiO 2 reddish pigments were uniform and well dispersed in solution. In addition, the pigments with different shell thickness were also prepared, and the effect of shell thickness on the color performance of the pigments was discussed.
