In this paper, a quaternary system of Mn0.43Ni0.9CuFe0.67O4 NTC thermistor ceramics prepared by solid/solid reaction were sintered by microwave and conventional method, respectively. In order to characterize the sinterability of the samples, the densification parameter, porosity and grain size distribution of the bulk were determined. The crystal structure, phase compositions, morphology and impedance of the samples were analyzed with XRD, SEM, EDS and impedance analysis. The experiment results confirmed that the sinterability and electrical properties of ceramics are homogenously improved by microwave sintering.
