Title:
MANUFACTURE OF GAS SENSOR
Document Type and Number:
Japanese Patent JPH04289447
Kind Code:
A
Abstract:

PURPOSE: To keep the amount of a catalyst layer uniform, to avoid the occurrence of cracks in the catalyst layer and to make it possible to maintain stabilized sensitivity all the time.

CONSTITUTION: A glass substrate 10 is fixed to the approximately central part of the surface of an insulating substrate 4 having a heater 7. A gas sensitive body 11 is provided on the surface of the glass substrate 10. The gas sensitive body 11 responds to the concentration of gas in surrounding atmosphere under the state wherein the gas sensitive body 11 is heated by the heater 7. Catalyst slurry is applied so as to cover the gas sensitive body 11, and a catalyst layer 14 is formed. The catalyst slurry is formed by adding ethylene glycol which is dihydric alcohol as an adjusting binder into catalyst powder supported with Pd-based alumina.
