This paper presents synthesis of calcium cobaltites of the nominal composition of Ca3Co4O9 prepared by the solid state reaction. The reaction between CaCO3 and Co3O4 was investigated at 700–900 °C during 20 h and at 800 °C during 2–30 h. Mass c

Starting powders of CaCO3 with different Ca:Co ratio and three different sources of cobalt (II,III) oxide were mixed and calcined at 700–1100 °C. DTA/TG, mass changes, density, grain size distribution, phase composition were examined. It has been
