Preparation Study of WO₃ Nano-Powder with Micro Emulsion Method

Abstract:

WO3 nano-powder was prepared by CTAB/n-buoh/octane/H2O micro emulsion system, Na2WO4 and hydrochloric acid as raw material. And the structure, size and topography of WO3 nano-powder were characterized with X-ray diffractometer, transmissive electron microscopy. The result showed:calcination temperatures and different reactant types affect WO3 characteristics evidently; In moisture content 8%, calcining temperature 400°C conditions, small particle size、distribution uniform and spherical shape WO3 nano powder with micro emulsion method is prepared.
