Abstract

Le procédé faisant l'objet de la présente invention consiste à produire une solution précurseur d'oxyde de tungstène par conversion d'une solution de péroxypolytungstate en une solution de polystungstate d'oxyde stable. La solution précurseur peut ensuite être transformée en oxyde de tungstène doté de propriétés électrochromatiques.
