Glasses have been made in the systems and with contents ranging between 50 and 87 mole%. The glasses were found to be semiconductors, those with the highest contents having a specific conductivity of the order of 10−5 ohm−1 cm−1 at room temperature. The relationship between the specific conductivity, σ, and the temperature was determined, and it was found that the slope of the plots was equivalent to an activation energy in the range 0.35–0.40 ev for all the glasses. The value of plotted against the mole percent gave a straight line relationship for each series of glasses. Conductivity values obtained could be easily reproduced and were not sensitive to variations in melting conditions.
