Abstract
L'invention concerne un procédé électrochimique destiné à la production de particules de l'ordre du nanomètre à partir d'un composé métallique. Ce procédé comporte les étapes suivantes : la dissolution anodique de métaux dans une cellule d'électrolyse, la solution électrolyte contenant une composante de précipitation qui, avec les ions métalliques se formant, permet d'obtenir un composé difficilement soluble, et un produit de modification de surface de manière à obtenir des particules à surface modifiée du composé métallique ou un précurseur de celui-ci ; éventuellement la séparation des particules formées de la solution électrolyte et éventuellement la calcination des particules formées. Le procédé est exempt d'eau et donc écologique et économique. Les particules de l'ordre du nanomètre produites sont aisément redispersées dans des milieux organiques et aqueux et ont une grande pureté. La taille des particules peut rester nettement en deçà de 100 nm. Ce procédé convient particulièrement à la production d'oxydes métalliques simples comme l'oxyde de fer et des oxydes métalliques binaires comme ITO et ATO.
