Anhydrous zinc antimonate semiconductor gas sensor and method for producing the same |
摘要 |
A sensor for detecting a gas comprises a gas detecting portion comprising an anhydrous zinc antimonate semiconductor. The sensor for detecting a gas is preferably hydrogen sulfide. A method for producing the sensor for detecting a gas comprising the steps of: mixing a zinc compound with colloidal antimony oxide in a ZnO/Sb2O5 molar ratio of 0.8 to 1.2; calcining the mixture at 300 to 680° C. and grinding the mixture to form electroconductive anhydrous zinc antimonate powder; preparing a sol of the electroconductive anhydrous zinc antimonate; coating the sol of the electroconductive anhydrous zinc antimonate on a substrate of a device; and heating the substrate at a temperature exceeding 680° C., but below 1,000° C.
