摘要
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 heatsensitive property of (PbSr)TiO_3based 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 semiconductivity of this material.
