Lead-free positive temperature coefficient thermistor material with high Curie temperature and preparation method thereof
The invention discloses a lead-free positive temperature coefficient thermistor material with high Curie temperature. The Curie temperature (higher than 120 DEG C) of the BaTiO3-based PTC semiconductor ceramic material is adjusted by adding Na2CO3, Bi2O3 and TiO2, lead oxide or lead salts are prevented from being introduced into a traditional formula, the Curie temperature of the BaTiO3-based PTC ceramic material is increased by taking lead as a moving agent, and the problem of environmental pollution caused by lead is solved.
本发明公开了一种无铅高居里温度的正温度系数热敏电阻材料。采用加入Na2CO3、Bi2O3和TiO2调整BaTiO3基PTC半导体陶瓷材料的居里温度(﹥120℃)，避免采用传统的配方中引入铅氧化物或铅的盐类，以铅元素作为移动剂来提高BaTiO3基PTC陶瓷材料的居里温度，解决了铅对环境造成的污染问题。
