摘要:
用传统高温固相法制备了锆钛酸钡BaZr0.2Ti0.8O3(BZT)掺杂的铌酸钾钠K0.5Na0.5NbO3(KNN)无铅压电陶瓷,研究了不同BZT掺杂量和烧结温度对KNN陶瓷微观结构、形貌和电学性能的影响。结果表明:从样品的X射线衍射图谱可以看出,全部样品均呈现出主晶相正交钙钛矿结构,但随着BZT掺杂量的增加,样品中的第二相的含量逐渐增多; 从样品的形貌分析中可以看出,掺杂BZT的样品晶粒明显较大,且晶界清晰,其样品的平均晶粒尺寸随着BZT掺杂量的增加和烧结温度的升高有逐渐增大的趋势; 对比不同掺杂量和不同烧结温度下制备的样品的综合性能,在1 150 ℃下烧结的BZT掺杂量为5%的陶瓷具有较好的形貌和优良的综合电学性能,即具有较为均匀的晶粒大小、清晰的晶界,最大的相对介电常数和较小的介电损耗,最大的压电系数。
Abstract:
BaZr0.2Ti0.8O3(BZT)Doping K0.5Na0.5NbO3(KNN)lead-free piezoelectric ceramics were prepared by traditional high temperature solid phase method.The effects of BZT doping amount and sintering temperature on the phase structure,microscopic morphology and electrical properties of KNN ceramics were investigated.The results show that all ceramics show the major crystalline phase of orthorhombic perovskite structure.The proportion of second phase increases with the increase of BZT doping amount.BZT doping samples exhibit large grain and clear grain boundaries.The even grain size is increasing with BZT doping amount and sintering temperature increasing.A comparative study of the comprehensive properties of the samples prepared with different doping contents and sintering temperatures reveals thatthe ceramic of BZT doping with 5mol% sintered at 1 150 ℃ possesses the best possible shapes and electrical properties:more uniform grain size,the largest relative dielectric constant and the smaller dielectric loss,as well as the largest piezoelectric coefficient.
