摘要
通过化学工艺制备（Ｓｒ，Ｐｂ）ＴｉＯ３半导体陶瓷，首次获得了与ＢａＴｉＯ３陶瓷相类似的典型ＰＴＣ特性，样品耐压强度大，室温电阻率低于１０２Ω．ｃｍ，升阻比高达１０６．３３，烧结温度可以降低至１１００℃以下。
Semiconducting (Sr,Pb)TiO 3 ceramics with a typical PTC effect like BaTiO 3 has been made by chemical processing for the first time.The PTCR jumps as great as 10 6.33 and the room temperature resistivity is lower than 10 2Ω·cm,The withstand voltage strength is above 330Vac/mm and the sintering temperature is lower than 1100℃.
