Abstract
PURPOSE: To obtain a gas detecting element which has a high detecting sensitivity and is excellent in high temperature stability and selectivity, by providing a silica- alumina compound layer carrying metal oxide on the gas sensor consisting of a metal oxide semiconductor, as a catalyst layer.
CONSTITUTION: The catalyst is formed by containing metal oxide such as chromium, cobalt, copper, nickel, manganese, etc. by about 0.1W20wt% in silica-alumina compound. Subsequently, paste which has been obtained by adding a binder to a metal oxide semiconductor such as ZnO-Cr2O3 compound, etc. is applied on the out circumferential surface of the cylindrical insulator 1 equipped with electrodes 2, 2, it is dried, after that, it is baked at about 300W1,000°C, and the gas sensor 3 is formed, and in addition, paste of the above-mentioned catalyst is applied and dried, and the catalyst layer 5 is formed by baking it at about 300W800°C, which is made a gas detecting element 4.
