X-ray study of amorphous anodic tungsten oxides

X-ray diffraction investigation in amorphous anode tungsten oxides is carried out. It is determined that in this oxide a close order corresponding to position of atoms in WO · 1/3A2O crystal structure appears. Exceeding of coordination numbers at the second and the first coordination spheres may result from additional substitution of oxygen atoms in the lattice for OH group or H2O molecule at retention of WO3 · 1/3H2O main motive. 24 refs.; 5 figs.; 3 tabs
