EFFECT OF HIGH-TEMPERATURE SODIUM ON THE MECHANICAL PROPERTIES OF CANDIDATE ALLOYS FOR THE LMFBR PROGRAM. Quarterly Progress Report, July--September 1967.

Development of an Electrochemical Oxygen Sensor for Liquid Sodium Using a Yttria Stabilized Zirconia Electrolyte

“…Equation 7 is a relationship between cell Emf, temperature, and oxygen activity in sodium. The activity of sodium oxide dissolved in sodium is related to concentration by the activity coefficient, γ, by the equation [ [12][13][14][15][16][17][18][19][20] Finally, at low concentrations seen in sodium, γ is roughly constant (γ ≈ γ o ). These substitutions can be made to Equation 7and the following relationship between oxygen and sensor voltage can be acquired:…”
