| 摘要 |
The present invention concerns a method for producing particles (10), comprising the following steps: introducing, into a reaction chamber, at least one reaction flow (1) comprising a first chemical element (typically silicon) and propagating in a direction of flow (11); projecting a radiation beam (3) through the reaction chamber, intersecting each reaction stream (1) in one interaction area (14) per reaction flow, to form, in each reaction flow, particle cores comprising the first chemical element; and introducing, into the reaction chamber, a second chemical element (for example carbon) interacting with each reaction flow (1) to cover the particle cores with a layer comprising the second chemical element. Each reaction flow (1) is preferably free of any agent oxidising the first chemical element. Preferably a ratio of one atom of the second element is introduced per unit of time for at least two atoms of the first element introduced per unit of time. The second element is preferably introduced in at least one confined flow (2). |
