Title (EN) FINE PARTICLES
(FR) PARTICULES FINES
Abstract:
(EN) A fine particle comprising a core and a coating, wherein the coating comprises a substantially monomolecular layer of organic molecules. The fine particle being produced by a process comprising introducing a core material into a plasma stream, thereby vapourising some or all of the core material; cooling the core material downstream from where the core material was introduced thereby creating particles of the core material; and coating the particles of the core material with organic molecules in an injection zone, wherein the injection zone is downstream of a region where the particles of core material are formed, or wherein the cooled particles of core material are coated with organic molecules in a coating chamber by applying a liquid coating material and/or a solution of coating material to the core material; where in the coating chamber is downstream of a region wherein the particles of core material are formed.
(FR) L'invention concerne une particule fine comprenant un cœur et un revêtement, le revêtement comportant une couche sensiblement mono-moléculaire de molécules organiques. La particule fine est produite par un processus qui comporte les étapes consistant à introduire un matériau de cœur dans un flux de plasma, ce qui vaporise ainsi tout ou partie du matériau de cœur; à refroidir le matériau de cœur en aval du lieu où le matériau de cœur a été introduit, ce qui crée ainsi des particules du matériau de cœur; et à revêtir les particules du matériau de cœur de molécules organiques dans une zone d'injection, ladite zone d'injection se situant en aval d'une région où sont formées les particules de matériau de cœur, ou bien les particules refroidies de matériau de cœur sont revêtues de molécules organiques dans une chambre de revêtement par application d'un matériau liquide de revêtement et/ou d'une solution de matériau de revêtement sur le matériau de cœur; ladite chambre de revêtement se situant en aval d'une région où sont formées les particules de matériau de cœur.
