It is shown that decomposition of a nonequilibrium quenched solid solution of sodium in ammonia occurs diffusively in two stages: In the temperature range 105–120°K the second stage of time decomposition occurs with an activation energy of 0.4 eV, which is twice the activation energy of the first decomposition stage in the temperature range 75–90°K. The mechanism proposed previously for interpretation of the features of electrical conductivity in solutions of sodium in ammonia is confirmed by an independent series of experiments. It is found that the kinetics of the increase with time of the resistance in solutions of potassium and calcium in ammonia differ from those determined for sodium. In lithium solutions quenched from the liquid phase no time dependence of resistance at a temperature of 77°K was observed. Resistance as a function of temperature for potassium, lithium and calcium also differs from the sodium case.
