固相法制备Pb0.955Pr0.03(ZryTi1-y)O3(PPZT1)和Pb1-1.5xPrx(Zr0.54Ti0.46)O3(PPZT2)系压电陶瓷,其中:x=0.02,0.04,0.06,0.08; y=0.51,0.52,0.54,0.56,0.58,0.60.XRD分析表明:PPZT1系统的准同型相界在锆的摩尔分数为55%左右.当锆的摩尔分数为54%,烧结温度为1 240 ℃,保温1 h,能获得优良的性能,其值分别为:d33=420×10-12 C/N; εT33/ε0=2 000;θC=314 ℃;Qm=76;tanδ＝2%;Kp=0.53.XRD分析还表明:PPZT2系统已远离相界,组成均在四方铁电相内.尽管PPZT2系统的介电常数很高,其压电性能却低于PPZT1系统.
