Abstract: front page image
(EN)A process for the production of powders by precipitation from a liquid reaction mixture comprises passing along a tubular reactor a segmented reaction flow comprised of discrete volumes of the reaction mixture separated by discrete volumes of a separating fluid which is substantially immiscible with said reaction mixture, the residence time of said discrete volumes of reaction mixture in the reactor being sufficient for the precipitation reaction to be effected.
(FR)L'invention concerne un procédé de fabrication de poudres par précipitation à partir d'un mélange réactionnel liquide. Le procédé consiste à passer le long d'un réacteur tubulaire un flux de réaction segmenté composé de volumes distincts du mélange réactionnel séparés par des volumes distincts d'un fluide séparateur essentiellement immiscible avec le mélange réactionnel, le temps de séjour des volumes distincts de mélange réactionnel dans le réacteur étant suffisant pour que la réaction de précipitation s'exerce.
