    摘要： The invention relates to a method of producing a gas sensor element having a porous film formed by a thick-film technique on a ceramic substrate surface so as to cover selected portions of electrode films precedingly formed on the substrate surface. The electrode material is a noble metal such as platinum. Both the electrode films and the gas sensitive porous thick-film are formed by known methods. To improve the contact between the gas sensitive porous thick-film and the electrode films both mechanically and electrically and stabilize the internal resistance of the sensor element by depositing a noble metal such as platinum at the interface between the porous thick-film and each electrode film, the porous thick-film is impregnated with a solution of a noble metal compound such as chloroplatinic acid and thereafter maintained in a reducing gas atmosphere having a controlled humidity in the range from 5 to 90% (relative humidity) at a temperature in the range from 10.degree. C. to 135.degree. C.

    摘要： A gas sensing element, such as may be used to sense the presence of oxygen contained in the exhaust from a burner or internal combustion engine, whereby, by preventing the re-sintering of functional layers of the sensing element, a deterioration of the performance of the element under high-temperature operating conditions is prevented. The inventive sensing element includes a ceramic susbtrate, an electrode layer formed on the ceramic substrate, a first functional layer overlying the ceramic susbtrate and the electrode layer and which contains a transition metal oxide as a main component, and a second functional layer that cover the first functional layer and which contains 1 to 30 wt % of an anti-sintering agent and has a transition metal oxide as a main component.

    摘要： A gas sensor has a ceramic substrate carrying a pair of electrodes embedded therein, which substrate has an opening bored at a surface portion thereof so as to expose tip portions of the electrodes. A thick gas-sensitive film is provided at the opening in such a manner that a gap between the electrode tip portions is filled by the gas-sensitive film while the metallic material of the electrodes is caused to precipitate on the boundary between the electrodes and the gas-sensitive film, so that the performance characteristics of the sensor is stabilized and its durability is improved.

    摘要： A laminar gas-sensitive thick film consisting of ceramic semiconductor and metallic catalyzer is formed across a pair of electrodes carried by a ceramic substrate, and the nature of metallic catalyzer on an outer surface layer of the thick film is different from that of metallic catalyzer in that portion of the thick film which is in the proximity of the electrodes.
