- W808898771 abstract "以传统电子陶瓷工艺制备了（K0.5Na0.5）1-2xSrx（Nb0.94Sb0.06）O3无铅压电陶瓷,研究了适量锶、锑取代对陶瓷结构及电性能的影响.结果表明,少量的锶、锑取代没有改变（K0.5Na0.5）NbO3陶瓷的相结构,仍为单相正交结构的钙钛矿型铁电体;适量的锶取代使得晶粒大小均匀一致,提高了陶瓷的致密度;锶、锑取代降低了陶瓷的居里温度,但对正交-四方相变温度的影响不大,且在0~200℃的温度范围,介电常数几乎不依赖频率的变化而变化;在x=0.008处,得到较好综合性能的陶瓷材料：d33=155pC/N,kp=0.361,Qm=120,Np=2862,Pr=23μC/cm2,Ec=1.4kV/mm,ρ=4.411g/cm3." @default.
