Abstract
dc.description.abstract
We report on the preparation of WO3 nanostructures using tungsten wire and iron wool in a domestic
microwave oven. Pure WO3 nanoparticles were octahedral or rhombohedral while iron containing
nanoparticles were spheroidal. Nanoparticles of monoclinic and cubic WO3 were found in the interior of
burned commercial light bulbs, where they grow by a spontaneous reactive gas condensation process. This
process was emulated heating a W filament under N2 inside a glass bell jar with a small air leak.
