Sažetak
Samples of zinc oxide with metal excess ZnO+xZn are made by sintering. The electrical dc and ac conductivity is measured in the temperature range from 300 K to 800 K and in the frequency range from 50 Hz to 500 kHz for three different x values. The activation energies and preexponential factors are estimated and the possible conductivity mechanism is suggested. The current–voltage characteristics measured in a reaction proceeding at ZnO+xZn electrode provide evidence of its electrochemical behaviour.
