From acid solutions obtained by dissolution of molybdenum or tungsten metal and V2O5in hydrogen peroxide solution, pure and well-crystallized phases have been prepared under the general formula HxVxMo1−xO3·0.3H2O (0.06 ≤x≤ 0.18) and H0.27V0.27

The local and medium range order in amorphous tungsten oxides has been investigated by anomalous wide-angle X-ray scattering (AWAXS). Amorphous phases have been prepared for the first time by non-reactive grinding, from both WO3 pyrochlore-type struc
