掺杂和烧结对(SrPb)TiO_3基陶瓷复合热敏特性影响的研究

STUDY ON EFFECTS OF DOPE AND SINTERING ON COMPOUND HEATSENSITIVE PROPERTY OF (PbSr)TiO_3

采用正交实验法，研究了Ｙ含量、ＳｉＯ２含量、烧结温度及保温时间对（ＳｒＰｂ）ＴｉＯ３基陶瓷复合热敏特性的影响。实验结果表明：烧结温度是影响最低电阻率的关键因素，Ｙ含量对材料的正、负温度系数影响最大，ＳｉＯ２在一定量范围内对促进材料半导化是有利的。

he effects of Y content,SiO_2 content,sintering temperature and socking time on compound heatsensitive property of (PbSr)TiO_3based ceramics is studied by cross experiment.The result shown that sintering temperature is the key factor of effecting the smallest specific resistance,Y content is the main factor of effecting positive and negative temperature coefficient,the proper SiO_2 content is favorable to semiconductivity of this material.
