The electrical conductivity was measured by using alternating-current conditions at frequencies of between 0.5 and 20kHz. It was found that, at 25C, the ionic conductivity was 0.15S/cm. Overall, the conductivity could be described by the expression:

σT (SK/cm) = 8300 exp[-0.134(eV)/kT]

The Haven ratio at temperatures of between 100 and 400C was equal to 0.9.
