In this paper, a B-site precursor method was adopted in the preparation of the PbZr0.47Ti0.5(Mn1/3Sb2/3)0.03O2 piezoelectric ceramics ternary system. Reaction mechanism and processing of PZT-based ceramics prepared by B-site precursor method were studied by using analysis method such as XRD, SEM, BET. B-site precursor reacts with PbO forming PZT phase. Composite with second oxide phase was then prepared. The effect of the sintering conditions and A and B-site precursor composition on dielectric and piezoelectric properties was investigated.A single phase of B-site precursor Zr0.47Ti0.5(Mn1/3Sb2/3)0.03O2 was calcined twice at 1340℃. X-ray diffraction indicated that the optimum calcinations condition of the PZT-PMS perovskite-phase was above 800℃. Micro-powder is achieved by conventionally small ball milling. The sintering temperature decreased with the increasing of Micro-powder, and the optimum sintering temperature was about 1240℃PZT composites with second oxide cphase were formed. The doping amount of oxide composites are 0-2%mol. Dielectric and piezoelectric properties of PZT was increased with increasing the doping amount.Precursor method and optimum MPB are used for preparing perovskite PZT-PMS ternary system piezoelectric ceramic. Higher dielectric and piezoelectric properties of the piezoelectric ceramics were achieved at last.
