摘要
采用电子陶瓷工艺制备了施主-受主共掺TiO2基压敏-电容双功能元件。电流-电压(I-V)以及阻抗-电压(Z-V)、相角-电压(-V)、电容-电压(C-V)、介电损耗角正切-电压(D-V)等阻抗谱分析表明,TiO2压敏陶瓷存在典型的极性特征,可通过"微极性区域"模型对其进行解释。
A donor-acceptor co-doped TiO2 varistor was prepared by typical electronic ceramic technology. According to the current-voltage(I-F) curve and the impedance spectroscopy curves such as impedance-voltage(Z-F), phase-voltage(J-F), capacitance-voltage(C-F) and dissipation-voltage (D-F) curves, the TiO2 varistor possesses polarization characteristics. The phenomenon can be clarified by the model of "micro-polarizing zone".
