Abstract
PURPOSE: To establish the gas detection element highly sensible and stable in sensitivity, by immersing tint in nitric acid of a given concentration and using stannic oxide obtained from white hydrate produced after baking at a specific temperature.
CONSTITUTION: Conc nitric acid is fed to tint so that the mol ratio of nitric acid is not less than 7 times to produce white hydrate. Next, after baking this white hydrate at 400W600°C, the baked material is milled to obtain SnO2 powder. Further, binder is suitably given to the said SnO2, the electrode 1 is inserted, and after pressing and molding a given cylinder, this is baked to obtain the gas detection element.
