摘　　要：研究了三元体系Bi2O3-ZnO-Ta2O5微波陶瓷的微波烧结情况,从烧结机理、陶瓷结构、显微形貌和介电性能等方面对微波烧结的样品和常规烧结样品进行了比较。实验结果表明,微波烧结大幅度缩短了烧结时间,并且很好地促进了Bi2O3-ZnO-Ta2O5陶瓷的致密化,制成的样品晶粒细小均一,且介电性能在一定程度上得到了优化。The Bi2O3-ZnO-Ta2O5 ceramics were prepared by microwave sintering and conventional sintering. The structure, surface and dielectric properties of the samples were measured and discussed. The results show that microwave sintering technique can shorten the sintering time and enhance the density of BZT ceramics comparing with the conventional sintering. At the same time, the dielectric properties of the samples were optimized.
