摘要
以ＢａＰｂＯ３为基的高Ｔｃ的ＰＴＣ热敏电阻材料，因含铅量高，预烧温度必须严加控制。通过扫描电镜及红外光谱分析，得出预烧温度以８４０℃为宜。
Pre-firing temperature for BbPO_3 used for PTC thermistors must be strictly controlled due to its high Curie point and high Ph content.It is concluded,through SEM and infrared optical spectrum analysis,that the optimized pre-firing temperature should be 840℃.
