Electrolytic Preparation and Evaluation of Tungsten Bronzes

Abstract

Mixed sodium-iron tungsten bronzes were electrolytically prepared from melts of tungstic oxide, sodium tungstate, and ferrous tungstate. The corrosion rate in 1F KOH appeared to be directly proportional to the oxygen partial pressure. Results of galvanostatic steady-state experiments for oxygen electroreduction in acid solutions are in agreement with existing knowledge that the rate determining step (r.d.s) is a charge transfer step. In KOH, r.d.s is not a simple charge transfer but some other process.
