摘　　要：以MnO2及MnCO3为锰的引入源,研究了锰的引入形态对Mn-Co-Ni三元系NTC热敏陶瓷电性能的影响。结果表明:锰的引入形态对材料的阻温特性无根本的改变,但对材料的室温电阻及B值有很大的影响,且随着MnCO3含量的增加呈U型变化。MnO2 and MnCO3 were used as the sources of manganese. The influences of adding form of manganese on the electrical properties of NTC thermistor (Mn-Co-Ni system) were investigated. The results indicate that adding form of manganese has no remarkable effect on R-T characteristic; has great influence on room temperature resistance and the B-value. These properties appear U-type transformation with the increase of MnCO3 amount added.
