For ceramic tiles, pigments give a stable coloration to a glaze, through a simple mechanical disper-sion in the middle to be colored. The final color of each pigment is due to the addition of a chromophore ion (usually transition metals) into an inert matrix, or this ion may be part of the own matrix, as in the case of ferrites [1]. In this work, a ferrite pigment was synthesized with applicability as pigments, besides magnetic devices, semiconductors, sors method, which was developed by Pechini. This method consists of formation of a polymeric net starting from a polyhydroxy alcohol and an alpha-hydroxycarboxylic acid, with metallic cations homogeneously distributed throughout the matrix [4,5]. After synthesis, CaFe2O4 physical and chemical behavior was studied, verifying its stability as pigment under industrial conditions.also physical and chemical properties.mines not only stoichiometric and morphologic control but pigment should be insoluble in glazes (substrate) [3]. The chemical synthesis was based on polymeric precur-Keywords: Ceramic pigments; Pechini method; CaFe2O4; Spinel; Ceramics; Characterization methods 1
