Formation of Bi$_{2}$WO$_{6}$ nanocrystals under conditions of hydrothermal treatment

Nanocrystalline Bi$_{2}$WO$_{6}$ was synthesized by means of hydrothermal treatment. It was shown that the formation rate of bismuth tungstate nanocrystals was determined by the presence of clusters formed at the stage of precipitation and having the same structure as that of Bi$_{2}$WO$_{6}$, and the morphology of particles formed during hydrothermal treatment depended on the hydrothermal medium's pH.
