Ceramic materials CaCu3Ti4O12 were synthesized by solid-phase reactions technique. The sequence of chemical reactions during the synthesis has been determined. Phase CaCu3Ti4O12 appears at 700 °C. At 800 – 900 °C, the intermediate phases CaTiO3, CuTiO3 and Ca3Ti2O7 are formed. Calcium and copper tit...
