摘要：

A selective method has been suggested for the synthesis of highly dispersed powders of gamma-WO3 (monoclinic) and beta-WO3.H2O (orthorhombic) by the hydrothermal treatment of aqueous suspensions of peroxotungstic acid in temperature range 70-250 degrees C. The hydrothermal treatment of suspensions of peroxotungstic acid leads to formation of monophase beta-WO3.H2O at temperature up to 100 degrees C and monophase gamma-WO3 at 250 degrees C. The hydrothermal treatment in the temperature range 120-200 degrees C gives two-phase samples of gamma-WO3 and beta-WO3.0.33H(2)O (orthorhombic syngony). The obtained monophase and two-phase powders have been studied by X-ray powder diffraction, scanning electron microscopy, IR spectroscopy, thermal analysis, and diffuse reflectance spectroscopy.
