Perovskite-like high-temperature thermistor material with different A-site elements and preparation method thereof
The invention relates to a perovskite-like high-temperature thermistor material with different A-site elements and a preparation method of the perovskite-like high-temperature thermistor material. According to the material, the perovskite-like high-temperature thermistor material with different A-site elements is obtained from calcium carbonate, copper oxide, titanium dioxide, yttrium oxide, lanthanum trioxide and strontium oxide as raw materials by mixing, grinding, calcining, carrying out cold isostatic pressing, sintering at high temperature, and coating and burning an electrode; the constant of the material is B300 DEG C/500 DEG C = 5900K-11000K; and the resistivity is 6.01 * 10 < 5 > Omega cm to 3.2 * 10 < 9 > Omega cm at the temperature of 75 DEG C. The perovskite-like high-temperature thermistor material with different A-site elements is stable in performance and good in consistency, has an obvious negative temperature coefficient characteristic within the temperature range of 75 DEG C to 600 DEG C, and is suitable for manufacturing high-temperature thermistors.
