摘　　要：研究了在Ｆｅ３Ｏ４中引入ＮｉＯ、Ａｌ２Ｏ３复合陶瓷材料的晶相结构、电阻值－温度特性及热稳定性等。通过对铁离子氧化状态及淬火工艺的调整，可得到性能优良的宽温区热敏元件。The design principle, performances and features of the thick film NTC thermistors are represented. Of the thermistor,in the range of 0～100 ℃, the linear deviation is ≤0.25%, sensibility 40～50 Ω/℃, accuracy of interchangeability ±0.5 ℃. It is a new NTC element for the digitized electric household apparatus and production equipment.
