ABSTRACT:
A process for fabricating an active electrode for an oxygen sensor involves preparing a solution by dissolving an alkoxide of a metal constituting an oxide semiconductor or solid electrolyte in a mixture of a solvent and diethanol amine, adding chloroplatinic acid to said solution to obtain a precipitation, calcining and pulverizing said precipitation to form a micro-composite power of an oxide of said metal and platinum, and forming an electrode on said oxide semiconductor or solid electrolyte using said composite powder.
