<p>The subject of invention is the synthesis of nanowires of tungsten oxide W5O14 in the presence of nickel at temperatures under 1000 degrees Celsius. A procedure is presented for the synthesis of a highly homogeneous phase of the compound W5O14 from the vapour phase in the presence of nickel according to the method of chemical transport in a sealed quartz vial. As the second embodiment, a procedure is presented for the synthesis of the compound W5O14 in a flow- through reaction vessel. In both procedures, electrically conductive nanowire crystals of the compound W5O14 are obtained. The synthesis is taking place in the vapour phase with tungsten entering the reaction as a pure phase or via WS2 +/- x, where x is approximately 0, synthesised previously from elements and/or tungsten source may also be tungsten oxides WO3-y, where y is between 0 and 1, and nickel may enter the reaction via NiJ2, Ni(OH)2 and/or as atomic nickel.</p> |
