Description
Summary:A simple CaCu3Ti4O12 synthesis method by carbonate precipitation has been developed, which is not inferior to the known methods of precipitation from solutions. The optimum temperatures for the synthesis of powder (850 оС) and sintering of ceramics (1080 оС) have been found. The CCTO ceramic prepared has stable and fine electrical properties. In the frequency range of 1 kHz to 1 MHz, the ε’ value always is higher 104 with the dielectric losses, tan δ ~ 0.05–0.08. Such CCTO ceramic prepared by the сarbonate co-precipitation method with good electric properties should find applications in electric devices.
