| This paper shows that CaCu3Ti4O12 (CCTO) can be synthesized through the high-energy ball milling of CaO, CuO and TiO2 powders. The dielectric characterization of CCTO obtained mechanochemically as well as, for comparison, by a high-temperature method is presented. Moreover, it is illustrated that zirconium oxide in contrast to a metallic iron generated during milling processes improves the properties of CCTO in terms of ceramic capacitors. |
