Abstract:
     The sensor used for measuring the catalyst temperature in treatment of automobile waste gas is comprised of heat resistant hood, heat sensitive resistor and lead wires, the main ingredient of the heat sensitive resistor is (Al1-x-y Crx Fey)2O3, in which x y lies between 0.05 and 0.95, y/(x=y) lies between 0.05 and 0.6. The CaO, rare earth oxide, ThO2 and ZrO2 are added if necessary, and it is made by passing through the processes of mixing, baking, smashing, granules making and sintering.
