Abstract
The methods of vanadium dioxide synthesis were developed. The first one is based on the decomposition of vanadyl oxalate VOC2O4 obtained by the dissolution of vanadium oxide (V) in ethanedioic acid solution with consequent heating. The second one uses the magnetron sputtering of metallic vanadium with its consequent soft oxidation. Investigations of the transition temperature in vanadium dioxide influence by the material doping and adding MoO3, Bi2O3, SnO2, NiO, CuO, Co3O4 as well as by the presence of various gases and vapors in the atmosphere were made.
