要約
(EN)
The present invention addresses the problem of providing a method for producing microparticles. Composite microparticles are separated by mixing at least two kinds of fluids to be processed in a thin film fluid that is formed between approachable and separable opposing processing surfaces that relatively rotate, wherein the fluids to be processed are a metal fluid comprising at least two kinds of metal elements that are dissolved in a solvent in the form of metal and/ or metal compound and a fluid for separation containing at least one kind of separating substance for separating a composite substance comprising the at least two kinds of metal elements. The molar ratio between the at least two kinds of metal elements contained in the resulting microparticles is controlled by controlling the circumferential speed of the rotation at a confluence where the metal fluid and the fluid for separation merge at this time.

(FR)
L'invention a pour objectif de fournir un procédé de fabrication de microparticules. Au moins deux sortes de corps fluides parmi un fluide métallique dans lequel un métal et/ou un composé métallique est dissous dans un solvant, et qui contient au moins deux sortes d'éléments métalliques, et un fluide pour dépôt contenant au moins une sorte de matière de dépôt afin de déposer une matière composite contenant au moins lesdites deux sortes d'éléments métalliques, sont mélangés dans un fluide à film mince se formant entre des faces de traitement qui sont placées face à face et dont au moins une effectue par rapport à l'autre une rotation relative permettant un rapprochement/éloignement, et des microparticules de matière composée sont ainsi déposées. Le fluide métallique et le fluide pour dépôt confluent alors, la vitesse périphérique de ladite rotation au niveau d'une partie de confluence est régulée, régulant ainsi le rapport molaire entre au moins lesdites deux sortes d'éléments métalliques contenus dans les microparticules obtenues.
