Abstract

On a mis au point un procédé de production d'oxydes métalliques mélangés uniformes, tels que des mélanges supraconducteurs comprenant Y1Ba2Cu3O7-x, dans lequel lesdits métaux sont précipités sous forme d'oxalates obtenus à partir de solutions des métaux sous forme de sels d'un acide carboxylique dans un alcool.
