| 摘 要： | 研究了Ｙ－Ｓｂ，Ｌｉ－Ｍｎ，Ｓｉ－Ａｌ等元素以固相或液相掺杂对正温度系数热敏电阻（ＰＴＣ）材料性能的影响。实验结果表明，Ｌｉ－Ｍｎ液相掺杂可以提高材料ＰＴＣ效应及耐压值；Ｓｉ－Ａｌ液相掺杂可降低材料室温电阻率，提高材料耐压值，Ｙ－Ｓｂ液相掺杂可以降低材料室温电阻率，但ＰＴＣ效应有所降低

| Abstract: | The influence of the state of dopants (Y Sb; Li Mn; Si Al etc. elements) on the properties of PTC material was studied. The experimental results show that Li Mn doping in liquid phase can raise the PTC effect and the withstand voltage of the material; Si Al doping in liquid phase can decrease the resistivity of the material at room temperature and increase the withstand voltage; Y Sb doping in liquid phase can decrease the resistivity at room temperature but the PTC effect of the material is somewhat lowered. |
