Experimental study on the performance of solid electrolyte oxygen sensor with solid Fe/Fe₃O₄ powder reference electrode has been performed in air and lead-bismuth eutectic (LBE) environment. The effect of air in the reference cell on the sensor performance was made clear. The oxygen sensor worked well in both air and LBE environments under oxygen saturation condition in the temperature of 550°C - 600°C.
