The Research of Pt Heating Resistor Paste Used for Sensors Based on ZrO2

Article Preview

Abstract:

Pt is used as a heating resistor by sensors based on ZrO2. A heating resistor will directly influence the response rate and life expectancy of the sensor. The service life of heating resistor using pure Pt is very short , in order to improve the quality of resistor, this paper studies the addition of ceramic powder to Pt paste by intermittent thermal shock test of heating resistor slurry life, the method of square resistance test, and using SEM to observe the microstructure of Pt resistor. Then the reasonable Pt paste formula of heating resistor is obtained.
