The influence of different molten salt environments on formation of tungstates has been studied. Well crystalline and pure Bi2WO 6 have been prepared in potassium nitrite KNO2 (350°C), potassium chloride KCl (800°C) and mixture of potassium-sodium sulphates K2SO4-Na2SO4 (800°C), but ZnWO4 have been successfully synthesized in sodium nitrate NaNO3 (350°C), mixture of sodium-potassium chlorides NaCl-KCl (680°C), potassium chloride KCl (780°C) and mixture of potassium-sodium sulphates K2SO4-Na2SO4 (850°C). In photocatalytic studies, samples with higher surface area have better photocatalytic activity.
