Nanosize WO3 were synthesized by hydrothermal method using sodium tungstate and tungsten chloride as raw material and glycol and urea as assistant in strong acid system. The products were characterized by XRD,SEM and EDX,and the effect of hydro-thermal condition on the morphologies of nanosize WO3 were studied. The results indicate that the important influence of different raw materials on the morphologies of nanosize WO3 under the same hydrothermal conditions. The hex-WO3 was obtained with sodium tungstate as raw material and glycol as assistant reagent.
