| titleOfInvention | Microminiature palladium oxide gas detector and method of making same |
| abstract | Abstract of the Disclosure A microminiature palladium oxide gas detector and its method of manufacture. The detector comprises an extremely small coil of extremely fine wire such as platinum which is retained, sealed and insulated with an amorphous ceramic binder. The detector further comprises a catalyst applied to its exterior surface. The detector is manu-factured by winding the wire about a mandrel which is desirably molybdenum. The coil is then coated with the binder composition which preferably comprises reduced chromic and phosphoric acids. The binder is then cured to retain the coil and the mandrel is removed by etching or oxidation. The catalyst is then applied which is preferably palladium nitrate in a weakly acidic hydrolyzed solution which has been adjusted to a pH of about 3 with tertiary octyl amine. The catalyst is then dehydrated and calcined desirably using an automatic electronic pulse controlled machine to precisely adjust and control processing temperatures and times. When hydrolyzed palladium oxide is used as the catalyst, the processing temperature never reaches the point where the oxide becomes reduced to the metal. |
