Deep hypothermia perovskite type negative temperature coefficient thermistor material and preparation method thereof
The invention relates to a profound hypothermia perovskite type negative temperature coefficient thermistor material and a preparation method thereof, and the material is prepared by mixing barium carbonate and cobaltosic oxide as raw materials or mixing barium carbonate, cobaltosic oxide and nickel oxide as raw materials. The perovskite structure oxide material is synthesized through a direct solid-phase reaction method including ball milling, calcining, grinding, forming and high-temperature sintering. Tests show that the resistance material can work under the condition of 16 K. The electrical property parameters are as follows: Rho 16K is equal to 107 omega.cm, and Rho 7K is equal to 800 omega.cm. The temperature measurement temperature zone is between 16 K and 300 K, and the problem that the temperature measurement temperature zone of the deep hypothermia thermistor is narrow is solved. And meanwhile, the temperature measurement temperature area of the prepared thermistor can reach 16K to 300K. The use temperature zone is wide, and the cost is reduced due to the absence of rare earth elements. The method is suitable for space science and technologies such as space cold target detection, superconducting filtering and quantum communication.
本发明涉及一种深低温钙钛矿型负温度系数热敏电阻材料及其制备方法，该材料是由碳酸钡和四氧化三钴为原料进行混合或是由碳酸钡、四氧化三钴和氧化镍为原料进行混合，通过球磨、煅烧、研磨、成型和高温烧结的直接固相反应法合成的钙钛矿结构氧化物材料。经测试：该电阻材料可以在16 K条件下工作。其电性能参数为：ρ16K=107Ω·cm，ρ7K=800Ω·cm。测温温区在16 K~300 K之间，解决了深低温热敏电阻测温温区较窄的问题。同时制得的热敏电阻测温温区可以达到16K到300K。使用温区较宽，由于不含稀土元素也降低了成本。适用于空间冷目标探测、超导滤波、量子通讯等空间科学技术。
