High-temperature perovskite type negative temperature coefficient thermal sensitive ceramic material, thermistor and preparation method of high-temperature perovskite type negative temperature coefficient thermal sensitive ceramic material
The invention belongs to the technical field of ceramic resistance materials, and particularly relates to a high-temperature perovskite type negative temperature coefficient thermal sensitive ceramic material, a thermistor and a preparation method of the high-temperature perovskite type negative temperature coefficient thermal sensitive ceramic material. The thermal sensitive ceramic material is prepared by taking La2O3, Al2O3 and one of Pr2O3, Nd2O3 and Sm2O3 as raw materials and adopting solid-phase synthesis, the chemical composition of the thermal sensitive ceramic material is La0. 9B0. 1AlO3, and B is Pr, Nd or Sm. The thermal sensitive ceramic material has the negative temperature coefficient characteristic within the temperature range of 100-1500 DEG C, and is good in high-temperature stability and wide in temperature range.
