Abstract
The object of the invention is the synthesis of threadlike tungsten oxide WO, in the presence of nickel at a temperature lower than 1000° C. Represented is a procedure for the synthesis of a highly homogeneous phase of the WOcompound from the vapor phase, in the presence of nickel, by means of a chemical transport method in a closed quartz ampoule. As an alternative example, a procedure is represented for the synthesis of the WOcompound in a through-flow reaction vessel. Both procedures yield electrically conductive threadlike crystals of the WOcompound. The synthesis is performed in vapor phase. Tungsten enters the reaction as a pure phase or via WS, x≈4, previously synthesized from the elements, and/or the source of tungsten may also be tungsten oxides WO, 0≦y≦1. Nickel may enter the reaction via NiI, Ni(OH)and/or atomic nickel.
