| Abstract: | Co1.5-xMn1.2Ni0.3AlxO4(x= 0,0.02,0.04,0.06) NTC thermistor materials were prepared by the traditional solid-state reaction method.The effects of Al2O3 doping on the microstructure and electric properties of prepared materials were studied through XRD,SEM and several instruments for electrical properties characterization.The results indicate that Al2O3 doping shows little effect on the crystal structure of prepared materials.However,with increasing Al2O3 content,the grain size of the MnCoNi thermistor materi... |
