Abstract

PURPOSE: To prevent fluctuation of the resistance value of the gas-sensitive substance produced by adding Pd to the N-type metal oxide semiconductor daily and lapse of time while the reducing gas exists by impregnating the alumina sol into the surface of the gas-sensitive substance and then giving burning to the surface.
CONSTITUTION: The Pd or the compound to turn to the oxide of Pd is added preferably by 0.5W3.0 wt% as PdO to the powder of the N-type semiconductor like SnO2. Then the mixture added with the binder like the organic tin is formed in the form of a lump between electrode 3 and heat generator 4 and then burnt. The surface of gas-sensitive substance 2 thus formed is made porous due to the gas or the like produced by the decomposition of the binder through burning, and the water solution of the aluminium hydroxy chloride is impregnated into this surface. Thus substance 2 impregnated by the alumina sol can be burnt at about 500°C after drying.
