| 摘 要： | 本文研究了Ｎｂ_２Ｏ_５、 Ｙ（ＮＯ_３）_３、 ＴｉＯ_２、及 Ａｌ_２Ｏ_３、 ＳｉＯ_２对 ＢａＴｉＯ_３半导体陶瓷性能的影响。结果表明室温电阻率的波动随不同施主掺杂物量的改变而不同。Ｙ（ＮＯ_３）_３在较宽范围内变化时，试样的室温电阻率能保持较好的稳定性。同时对ＴｉＯ_２及Ａｌ_２Ｏ_３、ＳｉＯ_２都能提高ＰＴＣ效应的机理进行了解释。

| Abstract: | The effects of Nb_2O_3, Y (NO_3)_3, TiO_2, Al_2O_3 and SiO_2 on the property of semiconducting barium titanate ceramics were studied. The results showed that the variety of room temperature resistivity was different with the changing quantity in different donors. When the quantity of Y (NO_3)_3 changed largely, the room temperature resistivity changed little, and the mechanism of TiO_2, Al_2O_3, SiO_2 increasing the PTCR effect was also investigated. |
