Abstract: A method for manufacturing a catalytic combustible gas sensor is provided to increase sensitivity of the catalytic combustible gas sensor by causing an oxidation of relatively inflammable gas easily. A method for manufacturing a catalytic combustible gas sensor includes the steps of: preparing a mixture by mixing 65-75wt% of Al2O3 powder with 25-35wt% of titania nanotube powder in which platinum and palladium are dispersed; applying the mixture onto a platinum heater formed on an alumina substrate(3) to form a sensing device(6), and applying Al2O3 powder onto a separate platinum heater to form a compensation device(5); and fixing each of the alumina substrates having the compensation device and sensing device to catalytic combustible gas sensor support rods(2) using a spot welding machine and platinum wire(4). Further, the mixture is made by mixing 70wt% of Al2O3 powder with 30wt% of titania nanotube powder.

Abstract: PURPOSE: A highly selective semiconductor detecting material for detecting CO, a detecting sensor, a method for manufacturing the detecting sensor, and a method for detecting the concentration of CO using the detecting sensor are provided to precisely detect the CO gas in an atmosphere by adding V2O5, Pd, and ThO2 to SnO2. CONSTITUTION: SnO2 is pulverized by using a ball-milling so that fine particles having the size less than 1 micrometer are obtained. Then, a heat-treatment process is carried out in the temperature between 900 and 1000°C for two hours. Then, a catalysis additive, such as V2O5 and ThO2, is added to the SnO2. After adding water to the mixture, the mixture is pulverized by using the ball-milling. Then, the mixture is dried in a dry-oven. Al2O3 and PdCl2 are added the mixture. Then, a detecting material(4) is screen-printed on an alumina substrate(2) which is formed with an Au electrode(3) and a resistance heater line(1).
