摘要
研究了ＭｇＯ加入到含铅ＰＴＣＲ陶瓷中的作用。用碱土金属Ｍｇ２＋对（Ｂａ，Ｐｂ）ＴｉＯ３掺杂，在１２４０～１３００℃空气中烧结，获得工艺性能良好，烧结温度较低，电性能优良的ＰＴＣＲ陶瓷材料。试验结果表明：ＭｇＯ的加入降低了含铅ＰＴＣＲ陶瓷的烧结温度，抑制了ＰｂＯ的挥发。
The effect of MgO on (Ba,Pb)TiO 3 PTC ceramic is studed. The results show that with the adictive of MgO, better electric properties and processability can be acquired.(3 refs )
