GAS COMPONENT DETECTING ELEMENT AND DETECTOR

摘要

Disclosed is a method for producing a gas component detecting element for detectors which comprises a sintered body of particles of a metal oxide wich changes in electrical resistance depending on relative atmosphere of combustible components in an exhaust gas, catalyst particles being supported on the surface of particles of the metal oxide, the method comprising the following steps: preparing particles of the metal oxide, calcining the particles of the metal oxide, subjecting the calcined particles to a treatment for enlarging specific surface area of the calcined particles, supporting catalyst particles on the surface of the particles subjected to the enlargement treatment, and sintering the particles which support the catalyst particles. The detector which has the above-mentioned gas component detecting element is also disclosed.
