The electrical conductivity of magnesium and aluminium doped sodium chloride crystals are measured at 1 kHz as a function of temperature from 275 to 730°C with the help of an ac bridge. The results show that, unlike divalent defects, the conductivity of aluminium doped crystals is lower than those values of the pure crystals in the extrinsic range, suggesting strong association between the aluminium ion and the created cation vacancies.
