Abstract
The effect of characterization of Fe2O3 particles on the color of α-Fe2O3 powders was evaluated. Several kinds of commercial α-Fe2O3 powders for red pigment in porcelain products were used. Morphology and mean particle diameter of the powders were observed by transmission electron microscopy (TEM). Color of α-Fe2O3 powders was estimated by spectral reflectance measured using spectrophotometer. The impurity contents of the powders were analyzed using ICP and fluorescent X-ray analysis. These results indicated the color of α-Fe2O3 powders was dependent on particle size distribution and impurity contents of the powders.
