Advances in Perovskite Doping – SrTiO3 with Cobalt Ions

Abstract

This paper supports the point of research on doping of inorganic materials – in this case pigments – with various elements. Compounds on the basis of SrTiO3 with individually substituted titanium positions for cobalt ions have been prepared by the solid state reaction which was boosted by the mechanoactivation in advance. Calcination temperature and molar ratio of reactants were varied in order to study their influence on the pigment synthesis. Powders were characterised in terms of thermal behaviour and phase composition. Particle size distribution and application possibilities in ceramic glaze and organic binder along with colour properties were subsequently determined for selected samples. Prepared set of pigments SrTi1-xCoxO3 (x = 0.1-0.9) differed in characteristic according to diverse range of substitution and conditions of the synthesis.
