Abstract

The 0.8Ba($Zn_{1/3}Ta_{2/3})O_3$-0.2Ba($Co_{1/3}Nb_{2/3})O_3$ ceramics were prepared by conventional mixed oxide method. The structural properties of the 0.8BZT-0.2BCN ceramics with the sintering temperature were investigated by XRD and SEM. The 0.8BZT-0.2BCN ceramics had a superstructure reflection plane of (100), (200). Increasing the sintering temperature. the ordering parameter of B-site atoms were increased. The lattice constant of 0.8BZT-0.2BCN ceramics was 3.97${\AA}$. Increasing the sintering temperature, the average gram sizes were increased. In the case of the 0.8BZT-0.2BCN ceramics sintered at 1500$^{\circ}C$, the average grain size and bulk density were 1.56${\mu}m$, 6.93$g/cm^3$, respectively.
