Abstract

Abstract: In this article, rutile-perovskite multi-phase composite was produced using mechano-chemical method followed by calcination with metatitanic acid and GCC as raw materials. The relative parameters in mechano-chemical method, such as slurry concentration, grinding time and ball to powder ratio, and the relative parameters in calcination, namely calcination temperature and calcination time, were researched systematically in order to get the optimum value. The structure and morphology of the final product were characterized and the reaction mechanism was investigated. The final product, namely the rutile-perovskite multi-phase composite, has excellent pigment properties comparable to titanium white. It also has excellent performances in coatings and ceramic glaze. All of these prove that the produced rutile-perovskite multi-phase composite can be used extensively in industry due to its excellent pigment properties together with simple reaction conditions.
