| Abstract: |
| The (1-x)(Bi0.5 Na0.5) TiO3-x Ba(Ti0.9Zr0.05 )O3 (BNT-BZT)ceramics were prepared by oxidation solid state method. The doping amount x was 0, 0.04, 0. 05, 0.06 and 0.07. The effects of quasi homomorphic phase boundary of BNT-BZT ceramics and the relationship between microstructure and properties of ceramics were studied. The dielectric and ferroelectric properties of ceramics were also discussed. By exploring the influence of Ba(Ti, Zr)O3 (BZT) doping amount on the properties of BNT, it is concluded that when the doping amount=0.05, the samples with dense structure, good dielectric and ferroelectric properties can be obtained, which is of great significance for industrial research and production |
