Zeleneva O. Reduction of d-metal oxides in the medium of methanol

The objects are copper, vanadium, molybdenum, and tungsten oxides togethre with barium-yttrium cuprate; the aim is to find out a possibility and develop a method of synthesis of d-element oxides as well as changing their oxygen stoichiometry by reduction of higher oxides in non-aqueous medium of methanol and titanium tetrachloride at room temperatures; the methods include X-ray diffraction, optical microscopy, differential thermal analysis, atomic absorption spectroscopy, chemical analysis, inductive determination of magnetic susceptibility for superconductive phases; the new approach lies in finding out an opportunity of reduction of powder higher d-metal oxides at as low as room temperatures; the results are new methods of synthesis and regulation of oxygen stoichiometry at low temperatures theat have been protected by obtained patents; the field is inorganic chemistry.
