Abstract

PURPOSE: To prevent the erroneous poeration due to the humidity in the surrounding by producing a combustible gas sensing element.
CONSTITUTION: Powders of SnO2 and ZnO having a diameter of about 0.1 to 5 microns are blended at a ratio of about 30:70 to 70:30 (in weight ratio), and a platinum electrode is buried, followed by the molding process into a desired shape. Then, the sintering process is performed at about 800 to 1000°C for 0.5 to 3 hours thereby to produce a gas sensing element. This element exhibits no electric resistance change for the humidity within the use temperature range. As a result, in case the element is used in a gas leakage warning device, there is no fear of erroneous operations due to the detection of water vapors.
