Electrical properties of solid oxide electrolytes

“…Sievert's and Henry's laws are usually obeyed, although slight deviations near the solubility limit of oxygen in liquid copper have been noted. [294][295][296][297][298][299][300][301] Several problems are inherent in these measurements. Satisfactory conducting leads must be found that will withstand the highly corrosive liquid metals.…”

A New Design of Oxygen Sensor for Electromotive Force Measurement and Electrochemical Deoxidation by Using Oxygen Pump

“…Therefore, the temperature of the present oxygen concentration cell was regarded to be constant. Compared with other literature [3][4][5][6][7][8] listed in Table 1, it was noteworthy that an oxygen sensor with the liquidsolid electrode technique could specifically avoid possible contamination from wire metal element to target metals and improves the accuracy of the measurement.…”

“…Since 1933, Fischer and Ackermann proposed a new electromotive force measurement (EMF method) to investigate the Gibbs free energy for oxygen dissolution in liquid iron, cobalt, nickel and copper, the concept of the EMF method has been expanded to ranges of metals. [1][2][3][4][5][6][7][8] Kiukkola employed the stabilized zirconia solid electrolyte to measure the oxygen activity in liquid Cu-O system and Cu-Fe-O system. Furthermore, he also extended his results and suggested the possibility of investigating the standard free energy of formation of CoO by immersing the Ni/NiO and Co/CoO electromotive sensor simultaneously in the same copper bath.…”

Mixed Conduction in Solid Oxide Electrolytes.

“…Use of a solid oxide electrolyte in an oxygen partial pressure gauge [15][16][17], or as% a blocking electrode for the measurement of the partial ionic conductivity 'ion) in another oxide [16], or as a monitor for oxygen in liquid metal baths [18][19][20][21][22][23][24][25][26] or for the various other thermodynamic and kinetic measurements [6], the highest possible partial ionic conductivity in combination with the lowest possible pArtial electronic conductivity ( Ge) is generally required.…”
