Abstract:

The peculiarities of oxide phase formation processes under the pyrolysis of salt and polymer-salt compounds based on polyvinyl alcohol and molybdenum and tungsten salts acidified by nitric acid have been studied. For that samples were prepared by annealing in a temperature range of 100-600 degrees C and investigated by small-angle neutron scattering and X-ray diffraction methods. Similar samples with no polymer in their composition were studied for comparison. A size distribution of oxide phase particles, a specific surface area, a volume fraction and a mean particle size were found to be dependent on an annealing temperature and availability of the polymer. The characteristics of the above samples were compared with those of the earlier samples synthesized from solutions with a naturally established acidity. A mechanism of oxide particle formation under a thermal decomposition of the acidic compounds is provided. (C) 2004 Elsevier B. V. All rights reserved.
