It is found that B-Bi-O frit can reduce the sintering temperature and improve the electrical properties of TiO2 ceramics. The best comprehensive electrical properties with the nonlinear coefficient up to 8.9, the breakdown voltage down to 4.92 V/mm, the relative dielectric constant of 4.47*105 and the leakage current of 0.102 mA are achieved by sintering the ceramics doped with 3 wt% B-Bi-O frit at 1400 °C.

XPS spectra demonstrate the coexistence of Ti3+ ions, Ti4+ ions and oxygen vacancies in TiO2 ceramics. As a result, it can be concluded that the enhancement of the electrical properties of TiO2 ceramics is mainly attributed to the following aspects: on the one hand, B-Bi-O frit helps to produce liquid phase sintering, which would reduce the porosity while increase grain size and promote solid solution of Nb2O5 and ZnO in TiO2 ceramic.
