Effect of Bi1.5ZnNb1.5O7 Nanopowder on its Ceramic Properties
The Bi1.5ZnNb1.5O7 ( -BZN) ceramics were prepared by combining conventional solid synthesis (CS) and hydrothermal method (HTM). The emphasis was placed on the effects of doping nanopowder synthesized by HTM on the properties of -BZN ceramics. The results show that there is no effect of doping nanopowder on the sintering temperature and phase of -BZN ceramics. Therefore, with the increase of doping nanopowder, the density of ceramics decreases. Doped 10 wt% nanopowder, the ceramic sample sintered at 1000°C exhibits a well-crystalline phase and more excellent dielectric properties than others. At 1MHz, the observed value is about 148 and tan value is less than 3.365×10-4.
