Abstract
Electrical‐conductivity measurements were carried out on vitreous GeO2 and the conductivity was measured as a function of frequency and temperature in the following ranges: 1.5 Hz ≤ ν ≤ 108 Hz and − 180°C ≤ T ≤ 600°C. The results are discussed in terms of a phenomenological Debye theory, and it is concluded that the conductivity is due to ionic processes.
