63189-285 Electrochemical sensors for atomic or molecular species are constructed comprising a shaped body isostatically formed from a blend. The blend comprises an ionically conductive solid solution electrochemically sensitive to the species to be detected having a fluorite crystal structure. Such material comprises a metal oxide, preferably one having a fluorite crystal structure and, admixed with the metal oxide, an oxide of an element from group IIA or IIIB of the periodic table in an amount sufficient to render the blend ionically conductive. Following the isostatic formation of the shaped body, the body is not densified through thermal means. The sensors are especially useful for sensing in metallurgical melts and in other harsh environments. In applications directed to the sensing of oxygen, it is preferred to employ zirconium oxide as the metal oxide. |
