【Abstract】 The electronic characteristic oxygen pressure of self-made Yittia-stabilized Zirconia electrolytes was measured from 700℃ to 1100℃ using coulemetric titration of oxygen out of liquid Aluminium and silver.It is showed that the range of the electronic characteristic oxygen pressure at 900℃ are Pa Self-made ZrO 2 electrolytes can be used to determine the oxygen concentration in the carburizing atmosphere on which the effects of the electronic conductivity on cell emf.can be neglected;It can be realized that liquid aluminium can be used to measure the electronic characteristic oxygen pressure of ZrO 2 electrolytes at low temperature.更多还原
