Thermistor material and preparation method thereof
The invention relates to a thermistor material and a preparation method thereof. The thermistor material is composed of lanthanum trioxide, cobaltosic oxide, bismuth trioxide, basic nickel carbonate,manganous manganic oxide, nickel sesquioxide and kaolin. The formula does not contain Fe, so that high uniformity under a high-temperature sintering condition is ensured; the sintering temperature isrelatively low and is only 1300-1500 DEG C, so that a certain energy-saving advantage is achieved; raw materials are sufficient in China and proper in price, so that the large-scale production is notlimited by too high cost.
本发明涉及一种热敏电阻材料及其制备方法，所述材料由三氧化二镧、四氧化三钴、三氧化二铋、碱式碳酸镍、四氧化三锰、三氧化二镍、高岭土组成。发明的配方中不含Fe，保证了在高温烧结条件下均一性高；烧结温度较低，仅为1300～1500℃，具有一定的节能优势；原材料在国内充足，价格适宜，使其规模化生产没有太高的成本限制。
