Abstract

PURPOSE:To provide a highly sentitive cmbustible gas detecting element which is strong against mechanical shock and etc. by using a gas sensitive substance carring a mechanically strong porous sintering substance. CONSTITUTION:A pair of platinum electrodes 3 and 4 are buries into ferric oxide (Fe2O3) powder, and formed to a cylindrical shape. This is burnt for about 2hr at ca. 900 deg.C in the atmosphere to obtain a large strong porous sintering substance. Then the sintering substnce is soaked in an aqueous solution of ferrous sulfate (FeSO4.7H2O) or tin salt (SnCl4.5H2O), and the holes or the particle parts of the sintering substance are impregnated with the aqueous solution. Then this is burnt for about 2hr at ca. 550 deg.C in the atmosphere to attach the gas sensitive substance to the sintering substance forming gas sensitizer. A heater 2 is arranged to this gas sensitizer 1, and needed wirings are insralled. This is arranged on a resin base 13 to obtain a detecting element for combustible gas.
