Abstract

Cette invention se rapporte à des techniques chimiques utilisées en particulier dans le domaine de la production de microagrégats, qui constituent les plus petits groupes d'atomes, dont le nombre varie de deux à plusieurs centaines et qui possèdent des caractéristiques uniques. L'objectif principal du procédé et du dispositif présentés dans cette invention est de mettre au point une technique qui permet de fabriquer une large gamme de microagrégats avec des compositions définies, dans des conditions industrielles, avec un apport d'énergie comparativement faible et des rendement de produit final élevés. Pour atteindre cet objectif, notre procédé, qui est basé sur la vaporisation de matière contenant du carbone au moyen d'un arc électrique, entretenu par la connexion des électrodes à la source de puissance, entraînant l'extraction de microagrégats du produit de la décomposition thermique, par rapport au prototype, suggère d'utiliser, comme matière contenant du carbone additionnelle, la solution diélectrique d'au moins l'un des éléments du microagrégat dans un hydrocarbure liquide et, en même temps, les électrodes, dont une est constituée de graphite et les autres sont constituées d'une matière contenant l'élément du microagrégat.
