Abstract
PURPOSE: To provide a gas-sensitive element which has long life and preferable gas selectivity by providing a catalytic layer buried with a heater on the surface of the gas-sensitive element (metal oxide semiconductor).
CONSTITUTION: A binder is added to a metal oxide semiconductor (ZnO, Cr2O3, etc.). Electrodes 7, 7' are buried in the semiconductor, and the semiconductor is formed in cylindrical shape, and sintered at approx. 300W1,000°C to thus provide a gas-sensitive element 1. Then, the element 1 is inserted into a heater coil (such as, for example, platinum) 5, and thus fixed by a jig. Then, catalytic material (such as, for example, Pt, Rh, Pd, etc.) is carried in fine powder to thereby form a catalyst. This catalyst is coated on the outside of the element 1 to thereby bury the heater 5 so as to form a catalytic layer 6. Then, this sintered at approx. 300W 800°C to thereby obtain a gas-sensitive element.
