Abstract
A method for producing particles, includes the following steps: introducing into a reaction chamber at least one reaction flow including a first chemical element (typically silicon) and propagating in a flow direction; projecting a ray beam through the reaction chamber, intersecting each reaction flow in an reaction flow interaction area, in order to form, in each reaction flow, the cores of particles including the first chemical element, and introducing, in the reaction chamber, a second chemical element, interacting with each reaction flow in order to cover the cores of particles with a layer including the second chemical element. Each reaction flow is preferably free of an agent oxidizing the first chemical element.
