【摘要】 用ＰｂＯ、ＺｒＯ＿２、ＴｉＯ＿２等原料经固相反应烧结制备了ＰＺＴ基四元系压电陶瓷。ＸＲＤ、ＳＥＭ及密度测试表明，材料主晶相为四方晶系的Ｐ４ｍｍ群，烧结致密度较好。极化后的性能测试表明，材料具有高介电系数（ε＿ｒ＝２０１５），压电系数（ｄ＿（３３）＝５７８×１０￣（－１２）Ｃ／Ｎ），机电耦合系数（Ｋ＿（３３）＝０．８１）和良好的机械品质因数（Ｑ＿ｍ＝５４３．８），是压电高压装置的理想材料。更多还原

【Abstract】 Piezoelectric ceramics based on PZTceramics were prepared in solid state reaction withmixture of PbO,TiO₂ and ZrO₂ etc. XRD and SEMwere used to confirm that the main phase in thematerial was te tragonal PZT lattice. Measurementson polarized products indicated that dielectricconstant,piezoelectric constant,electromechaniccoupling factor and mechanical quality factor were ε_r=2015,d₃₃=578.06×10￣（-12）C/N,K₃₃=0.81 and Q_m=543.8,respectively.更多还原
