以熔盐法和质子取代法制备的片状Nb2O5粉体为模板晶粒,固相法合成的(Na0.8K0.2)05Bi0.5TiO3 (NKBT)粉体为基料,分别采用固相压制成型(干法)和流延成型(湿法)工艺制备出具有较高取向度的织构化NKBT无铅压电陶瓷,研究了两种成型工艺对NKBT无铅压电陶瓷的显微结构、压电性能和介电性能的影响.结果表明:采用湿法工艺制备的织构陶瓷的各项性能优于干法工艺,采用湿法工艺在1150℃保温5h时,可以获得较高织构度(f=0.66)的NKBT无铅压电陶瓷,并具有优异的压电和介电性能:压电常数d33 =149 pC/N,介电常数ε3T3/ε0=912和平面机电耦合系数kp=29.4％.
