ZnO linear resistors have anticipated application prospect in electrical and electronic industry, but the study of La2O3doping is still poor. In this paper, the ZnO linear resistors doped with Al2O3, MgO, SiO2and La2O3were prepared by the conventional solid-state sintering method, and the effects of La2O3doping on the microstructure and comprehensive electrical properties were studied. Structural and morphological characteristics of the samples were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD) respectively. The property of resistivity-frequency reveals that the samples could be applied in high-frequency electric field. The dielectric property indicates Maxwell-Wagner interfacial polarization exists in the matrixes. With La2O3content of 1 wt%, ZnO linear resistors have the best linear performance: the grain size is relatively uniform, the resistance temperature coefficientαTis − 6.63 × 10−3/°C, and the nonlinear coefficientαis 1.09. The comprehensive analysis of the influence of La2O3doping on the electrical properties is of important significance for preparing ZnO linear resistors with excellent electrical properties.
