Abstract(Bi2O3)(0.73)(Y2O3)(0.27) fine powders prepared by wet chemical precipitation method were cold isostatically pressed to form solid electrolyte tubes, and sintered at 900 degrees C for 10 h in the air. Their pumping oxygen characteristics in non-dehydrated Ar gas were investigated, where a ZrO2 (Y2O3 stabilized) oxygen sensor was used to measure the oxygen partial pressure Po-2. The results showed that the Po-2 Value reached magnitudes of 1x10(-20)-1x10(-10) Pa at the applied pumping oxygen voltage of 0.5 V, 1x10(-37)-1x10(-27) Pa at 1.0 V and 1x10(-53)-1x10(-47) Pa at 2.0 V within the temperature range from 550 to 650 degrees C. Moreover, no cracks were found in the tested solid electrolyte tubes. Thus, the Bi2O3-Y2O3 system might be used in solid electrolyte oxygen pump for purifying gases.

Moreover, no cracks were found in the tested solid electrolyte tubes. Thus, the Bi2O3-Y2O3 system might be used in solid electrolyte oxygen pump for purifying gases.
