中文摘要 | 采用传统固相法制备了Co1.5 xMn1.2Ni0.3AlxO4(x=0,0.02,0.04,0.06)NTC热敏电阻材料。借助XRD、SEM和几种电性能测试手段,研究了Al2O3掺杂对MnCoNi热敏电阻材料相结构及电性能的影响。结果表明:随着Al2O3掺杂量的增加,MnCoNi热敏电阻材料的晶体结构不变,晶粒减小,电阻率和材料常数B值由339.07Ω·cm、3489.07K分别增加到3723.89Ω·cm、3956.80K,电学稳定性由1.65%提高至0.17%。 |
英文摘要 | Co_(1.5-x)Mn_(1.2)Ni_(0.3)Al_xO_4(x=0,0.02,0.04,0.06)NTC thermistor materials were prepared by the traditional solid-state reaction method.The effects of Al_2O_3 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 Al_2O_3 doping shows little effect on the crystal structure of prepared materials.However,with increasing Al_2O_3 content,the grain size of the MnCoNi thermistor materials decreases,while the resistivity,material constant B value and electrical stability increase from 339.07Omega·cm,3 489.07 K and 1.65%to 3 723.89Omega·cm,3 956.80 K and 0.17%,respectively. |
