HIGH TEMPERATURE NEGATIVE TEMPERATURE COEFFICIENT THERMISTOR MATERIAL AND PREPARATION METHOD THEREOF
A composite thermistor material, a preparation method and an application thereof. The perovskite structure oxide and the pyrochlorite structure oxide are composite by solid state reaction method, which comprise process of ball milling, drying, and calcining. Then the thermistor ceramics with high temperature resistance and controllable B value are sintered at high temperature after mould forming, then the thermistor disks are coated by platinum paste, and then the platinum wire is welded as the lead wire to form thermistor element. The thermistor of the invention can realize temperature measurement from room temperature to 1000° C. and has good negative temperature coefficient thermistor characteristics. The thermistor coefficient B can be adjusted by changing the two-phase ratio to meet the requirements of different systems.
