Original Abstract

We deal with the investigation of electrical properties of CaCu3Ti4012 based ceramics, doped with transition metals and lanthanides. Attention is focused toward the identification of the mechanism leading to high dielectric constant. In the course of our investigations we would like to modify the CCTO ceramics in order to reduce dielectric loss and extend the frequency range in which the dielectric constant retains its high value, up to the GHz range. Partial objectives are the structural and dielectric analysis of the pseudo-perovskite structure and analysis of the suitability of different types of electrical contacts to these materials.
