The dielectric breakdown strength (Eb) of PZT95/5type ferroelectric ceramics is very important to their actual applications, however, the low Eb of PZT95/5 type ceramics becomes a critical limitation in their actual applications. In order to improve Eb of PZT 95/5 type ferroelectric ceramics from the perspective of fabrication technology, microstructure of the materials, dielectric breakdown properties and so on, this paper selected PZT95/5 ferroelectric ceramics as research object and explored the methods for improving the dielectric breakdown strength of PZT95/5 type ferroelectric ceramics. We used traditional solid state synthesis method and heterogeneous precipitation method to prepare PZT95/5 type ferroelectric ceramics with different microstructures and properties. The research showed that the dielectric, piezoelectric and ferroelectric properties of ceramics fabricated by the heterogeneous precipitation method are more outstanding than that of the ceramics fabricated by the solid state synthesis method. According to the theory that weakness induced dielectric breakdown, we used Weibull distribution to deal with the data of Eb and compared the Eb of every kind of ceramic samples by different routes.
