  • Method for producing submicron-sized particles including aluminum by laser treatment
    Patent number: 10227236
    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.
    Type: Grant

  • Process for preparing a silicon carbide part without the need for any sintering additives
    Patent number: 8871141
    Abstract: The invention relates to a process for preparation of a part comprising silicon carbide with an average nanometric grain size and a relative density of more than 97%, said process comprising: a preform formation step by cold compaction of a nanometric silicon carbide powder or the formation of agglomerates of such a powder by granulation of the powder; a spark plasma sintering step of said preform or said agglomerates, without the addition of sintering, at at least one predetermined temperature and pressure so as to obtain the required relative density and average grain size, namely a relative density of more than 97% and a nanometric average grain size.
