AbstractAs for traditional lead-based piezoelectric ceramics, different lead raw materials have minor effect on ceramic's properties. Meanwhile, poor electrical property is frequently observed in BiFeO3-PbTiO3 based ceramics due to their high leakage current. Here, Pb3O4 and PbO as two kinds of lead raw materials have been used for the preparation of BiFeO3-PbTiO3 based ceramics. The structure, composition, and electrical properties of the ceramics have been analyzed. Although both samples have the same phase structure, the BiFeO3-PbTiO3(PbO)sample exhibits better ferroelectric properties compared with the BiFeO3-PbTiO3(Pb3O4) sample due to the high conductivity in the BiFeO3-PbTiO3(Pb3O4) sample. Both EDS and XPS analysis can confirm the existence of Bi-rich grain boundary phase in BiFeO3-PbTiO3(Pb3O4) sample. In addition, it can be found that the concentration of oxygen vacancies and Fe2+ ions in BiFeO3-PbTiO3(Pb3O4) sample is significantly higher than that of in BiFeO3-PbTiO3(PbO) sample, which is in good consistent with the high conductivity in BiFeO3-PbTiO3(Pb3O4) sample. This result will be helpful to the suitable lead raw material for preparation of BiFeO3-PbTiO3 based piezoelectric ceramics with high resistivity.
