The thermal expansion of the ionically conducting silver iodide - silver molybdate glass (AgI)0.67(Ag2MoO4)0.33 has been investigated from low temperatures up to about the glass transition region using a capacitance dilatometer with a quasi-adiabatic method. The results do not show any anomalous behaviour in a temperature range where the existence of relaxation processes with peculiar features was previously revealed using mechanical spectroscopy, but rather a monotonic increase of positive values of the thermal expansion coefficient.
