摘要
CaCu3Ti4O12 （CCTO） ceramics doped with Zr^4＋ were prepared. Effects of Zr^4＋ on microstructure, dielectric properties and conduction behavior of CaCaCu3Ti4O12 （x=0, 0.05, 0.10, 0.20） ceramics were studied in the frequency range of 10-10^6 Hz. Grain size and dielectric loss of Zr^4＋-doped CCTO ceramic decreased compared with pure CCTO. The loss tangent （tang） of CaCu3Ti4O12 （x=0.20） ceramic droped to 0.05 at a frequency of 1 kHz, which was reduced by 55% compared with pure CCTO ceramic. The mechanism effect of electrical conductivity on dielectric loss of ZP^4＋-doping CCTO ceramics was also discussed.
