Abstract

CaCu3Ti4O12 and CaCu3Ti3.9Zr0.1O12 ceramics were prepared by the traditional solid-state reaction method and the dielectric properties were investigated. Comparison of the results of the two samples examined indicated that the partial replacement of titanium by zirconium in the system CaCu3Ti4O12 may result in different changes of the dielectric constant and dielectric loss. For these experimental phenomena possible explanations and predictions also have been presented.
