Title (EN) PROCESS FOR MAKING SOLID PARTICLES
(FR) PROCÉDÉ DE FABRICATION DE PARTICULES SOLIDES
Abstract:
(EN) The invention relates to a process of creating particles of controlled size by creating them in the interstitial regions in a continuous liquid phase that contains a second, inert gas phase at high volume fraction; namely a foam. The second phase creates a physical barrier that limits the aggregation of formed particles beyond the size of the narrow interstitial regions occupied by the continuous phase. This technique is useful when the particles normally create large aggregates due to the fast nature of the reaction and the strong attractions between the formed particles, and for enhancing the deposition of high-value materials by connecting them to coacervates of controlled size.
(FR) L'invention concerne un procédé de génération de particules de taille prédéterminée par génération de celles-ci dans les régions interstitielles d'une phase liquide continue qui contient une seconde phase gazeuse inerte à haute fraction volumique, à savoir une mousse. La seconde phase forme une barrière physique qui limite l'agrégation des particules formées de façon à la restreindre à la taille des étroites régions interstitielles occupées par la phase continue. Cette technique est utile lorsque les particules forment normalement de grands agrégats en raison de la nature rapide de la réaction et des fortes attractions entre les particules formées, ainsi que pour améliorer le dépôt de matériaux à valeur élevée en les reliant à des coacervats de taille prédéterminée.
