对常温阻值小于标称阻值ＰＴＣＲ热敏电阻在氧化气氛中（氧分压ｌｇＰＯ２＝－０．３３５７～－０．４９１４）于６００℃、８００℃、９００℃分别处理２ｈ、４ｈ、６ｈ，对处理后的热敏电阻电性能及老化特性进行了研究。结果表明，在满足产品电性能要求的前提下，氧化气氛热处理在一定程度上可以调整ＰＴＣＲ热敏电阻的常温阻值，提高产品的合格率
The resistance at room temperature is less than the nominal resistance PTCR thermistor in the oxidizing atmosphere (partial pressure of oxygen lgPO2 = -0.3357 ~ -0.4914) at 600 ℃, 800 ℃, 900 ℃ were treated 2h, 4h, 6h, The electrical properties and aging characteristics of the treated thermistor were studied. The results show that, to meet the electrical performance requirements of the premise, the oxidation atmosphere heat treatment to a certain extent, can adjust the PTCR thermistor room temperature resistance, improve the pass rate of products
