| 摘 要： | 以溶胶－凝胶一步法合成了含有改性剂Sb的BaTiO3基正温度系数电阻（positive temperature coefficient of resistivity,PTCR)陶瓷，着重讨论了改性剂Sb掺杂量的变化对PTCR陶瓷电学性能的影响。结果表明，随改性剂含量的增加，材料的室温电阻率（ρ室）、电阻－温度系数（α）、耐电压强度（VB.max)均呈现“W”形变化。

| Abstract: | As a modifier, antimony is doped in BaTiO 3 based PTCR ceramics prepared by Once through method in Sol Gel process. With the increase of antimony concentration, the W shaped electrical behavior has been observed. The effect of its concentration on electrical properties of PTCR ceramics has been discussed. |
