The electrical conductivities of P 4 O 10 ‐V 2 O 5 and P 4 O 10 ‐WO 3 glasses were compared. The P 4 O 10 content of a glass from each system was replaced by increasing amounts of several oxides. The conductivity of the vanadium phosphate glass was insensitive to oxide replacement, in contrast to the conductivity of the tungsten phosphate glass, which decreased by almost five decades when a small amount of V 2 O 5 was introduced. The change was attributed to the effect of oxidation‐reduction on the tungsten ions.
