Electronic Conduction and Electron Mobilities in Molten NaCl ‐ Na Solutions

The electronic conductivity of molten solutions was determined as a function of the activity of Na at 850° and 900°C by using the Wagner polarization technique. A transient technique was used to determine the diffusion coefficient and the mobility of electrons. A thermodynamic defect model was applied for calculating the concentration of defects as a function of the activity of Na in .
