Abstract:Under hydrothermal conditions, the rule was found for the preparation of superfine powder of pyrochlore - type tungsten trioxide by changing the pH value of the system, concentration of the acid, reaction temperature and time. The products were characterized by XRD, TG, IR and EPMA. The results reveal that the compound is the superfine powder of cubic pyrochlore-type tungsten trioxide with the particle size 24nm.
Keywords:pyrochlore  tungsten trioxide  hydrothermal synthesis  superfine particle
