Thermoelectric powers of zirconia base solid electrolytes and liquid PbO-SiO2 system have been measured in air in the temperature range from 700° to 1 600°C. Electrode at higher temperature side was the negative pole for zirconia electrolytes (oxygen anion conductor), whereas electrode at lower temperature side was the positive pole for molten PbO-SiO2 system (lead cation conductor).
The absolute thermoelectric powers of the oxide systems have been calculated by substracting the EMF of the virtual cell reaction and thermoelectric power of platinum electrode from the measured total electromotive forces.
Those are in range of -0.37 to -0.51 mV/K for the solid Electrolytes and of 0.06 to 0.013 mV/K for the liquid silicate. Physical meanings of these values arn dicussed.
