Abstract

WO₃ nano-powder was synthesized by micro-reactor method in CTAB/n-butyl alcohol/n- octane/H₂O microemulsion system and sodium tungstate and hydrochloric acid as reactants. Structure and properties of WO₃ nano-powder were characterized by X-ray diffractometer, transmissive electron microscopy and UV-vis. It is shown that the particle sizes, topography of the particles and phase structures of WO₃ nano-powder are changed with moisture content in the microemulsion system, calcination temperatures and different reactants, the sizes of WO₃ nano-powder increase with moisture content in the microemulsion system and calcination temperatures. The sizes of WO₃ particles obtained from ammonium tungstate as reactant are smaller than that sodium tungstate as reactant.
