## Abstract Conductivity spectra of mixed‐alkali ions in iron phosphate glasses have been studied in the frequency range from 400 Hz to 200 kHz, and over a temperature range from 333 K to 493 K. The ac conductivity as a function of temperature was divided into two domains; one where the absolute of
