摘要

In this paper, two kinds of piezoelectric powders (PZT and KNN piezoelectric materials) and varistor powders (ZnO-Bi2O3 based varistor materials) were used to prepared PZT-ZnO and KNN-ZnO multiple functional electronic ceramics with piezoelectricity and varistor behavior by traditional solid-phase sintering method respectively, which are denoted as ‘PZ’ and ‘KZ’ ceramic samples. The results illustrate that all PZ and KZ ceramic samples had both piezoelectric properties and varistor behaviors. There were two crystal phases of perovskite and wurtzite in these samples, which were identified by the composition and morphology via XRD, SEM and EDS detection methods. In particular, the ferroelectric tests of PZ ceramic samples proved that the multiple functional electronic ceramics have special hysteresis loops. PZ and KZ ceramic samples sintered at 1102  ℃obtained the best comprehensive properties that the d33 of 32 and 28 pC/N, and the E1mA of 1132 and 1383 V/mm, respectively.
