Performance of the oxygen sensors with solid and liquid type reference electrode (RE) were investigated in the liquid LBE. The oxygen potentials in the LBE were made equilibrium with the formation potentials of PbO and Fe3O4 at 450°-600°C. The stabilization time to an equilibrium condition of the RE of solid type RE was shorter than liquid type RE and both of the sensors perfomed well in the liquid LBE.
