Composite high-temperature perovskite negative temperature coefficient thermistor and preparation method thereof
The invention discloses a composite high-temperature perovskite negative temperature coefficient thermistor and a preparation method thereof.The composite high-temperature perovskite negative temperature coefficient thermistor is prepared from calcium carbonate, zirconium dioxide and manganese dioxide according to the chemical formula (1-x) CaMn0. 05Zr0. 95O3-xCaMnO3, 0 < = x < = 0.2. The preparation method comprises the steps that a, perovskite phase CaMn0. 05Zr0. 95O3 is prepared; b, preparing a perovskite phase CaMnO3; and c, combining perovskite phases CaMn0. 05Zr0. 95 O3 and CaMnO3 to obtain the composite high-temperature perovskite negative temperature coefficient thermistor which has the negative temperature coefficient characteristic within the temperature range of 100-1200 DEG C and has the material constant of B100 DEG C/1200 DEG C = 1848.3-11286.4 K. The invention also discloses a preparation method of the composite high-temperature perovskite negative temperature coefficient thermistor. The composite high-temperature perovskite thermistor with the negative temperature coefficient is excellent in performance and good in high-temperature stability, and can provide support for temperature measurement in special environments such as high temperature.
