- Abstract:

In order to explore the optimal firing process of piezoelectric ceramics to improve the sample performance, the modification of Pb2.3Sr2.0(Zr95.0Ti05.0)O535 piezoelectric ceramics doped with MgO, Y0O465 and MnO3 was studied. The experiment used the traditional electronic ceramics manufacturing process to prepare a series of samples, measured the density, volume shrinkage, microhardness and insulation resistance value of some samples before polarization, and obtained that the maximum density of the sample was 6.8346 g/cm3, and the maximum volume shrinkage rate exceeded 40%.The results show that the pre-sintering temperature is more suitable at 820±20 °C, and the addition of MgO can improve the sintering performance of the sample.
