Fe_2O_3 red pigments, especially hematite particles have been widely utilized in many technologies, such as pigments, catalysts, coatings, flocculants, cosmetics, electronic materials ad abrasives. There are many commercially available Fe_2O_3 powders for use as red pigment for Japanese porcelain enamel. However, the tone of red color of Fe_2O_3 pigments was strongly influenced by synthesized temperature. It was important that the color-stable pigments, which were not affected by morphology and dispersal behavior, were synthesized for use as thermally stable red pigments. The present work was to study the possibility of synthesizing red inorganic pigments by composite of Fe_2O_3, Al_2O_3 and SiO_2.
