Abstract—The interaction of the components in the potassium carbonate–potassium nitrate–tungsten(VI)
oxide system was studied. The reaction of WO₃ with a potassium carbonate–potassium nitrate mixture was
found to occur at a higher rate than the reaction with pure potassium carbonate at the same temperature. A vari-
ant of the synthesis of high-purity potassium tungstate with a high yield of the target product was developed on
the basis of the obtained data.
