Sensing element for catalytic combustion type gas sensor

摘要

The catalytic combustion type gas sensor includes a sensing element, a heat conducting layer of which includes boron nitride. The boron nitride content is from 30 wt % to 100 wt % of a material (such as alumina) that would be a base material having the highest proportion in a conventional heat conducting layer without boron nitride. A catalyst layer of the sensing element also includes boron nitride. The boron nitride content is from 10 wt % to 80 wt % of a material (such as tin oxide) that would be a base material having the highest proportion in a conventional catalyst layer without boron nitride.
