The electrical conductivity of iron‐containing silica glasses was measured from 80 to 350 K. The conductivity data were analyzed based on the hopping conduction theory. The hopping binding energy (W p ) and disorder energy W D ) were calculated from the activation energy at high and low temperatures. The disorder energy obtained was much lower than reported for FeO‐P 2 O 5 glasses, but similar to that for vandium‐containing glasses.
