| 摘 要： | 液相添加剂ＡＳＴ（Ａｌ２Ｏ３＋ＳｉＯ２＋ＴｉＯ２）对ＢａＴｉＯ３陶瓷材料电性能的影响很大，随着Ａｌ２Ｏ３含量的增加，材料的电性能降低；ＳｉＯ２、ＴｉＯ２的物理特性对材料电性能影响较大；过量ＴｉＯ２对材料ＰＴＣ效应有重要影响，适当过量ＴｉＯ２含量，可得到性能优良的ＰＴＣＲ陶瓷。

| Abstract: | The effect of liquid phase additives AST(Al 2O 3+SiO 2+TiO 2) on the electric properties of BaTiO 3 ceramics is researched. The results show that the electric properties will be impaired when Al 2O 3 be added, the more the worse, and strongly influenced by the physic properties of SiO 2 and TiO 2. Excellent PTC ceramics can be acquired by adding appropriately more TiO 2.(3 refs ) |
