Ceramic wafer of thermistor, thermistor and preparation method thereof
The invention discloses a ceramic wafer of a thermistor, the thermistor and a preparation method thereof. The ceramic wafer of the thermistor is prepared by sintering after molding mixture powder at the molding pressure of 50-500MPa by using a cold isostatic pressing molding process, wherein the mixture powder comprises transition metal oxide powder and rare earth oxide; the transition metal oxide powder comprises the following components in percentage by mole: 30-70% of Co3O4, 20-60% of MnO2 and 5-20% of CuO; the rare earth oxide is Y2O3 or La2O3; and the mass of the rare earth oxide is 1-10% of the mass of the transition metal oxide powder. The thermistor is prepared from the ceramic wafer of the thermistor, a pair of electrodes, a pair of leading wires and an insulated material. All the B value, rated electrifying current and impact-resistant capacitance of the prepared thermistor are relatively high.
