Abstract: A device and a method for producing suspensions or wet pastes of nanoparticles or ultra-fine particles. The method comprises: introducing a flow of particles of nanometric or submicronic size into a first compartment of a chamber having a bulk density between 15 and 100 g/L; forming, in the first compartment, a spray of droplets between 1 and 10 micrometres in size, by injecting a solvent in liquid or gas form into a second compartment of the device and passing said solvent through the filtering means, the solvent being chosen from the solvents which are liquid at ambient temperature and at atmospheric pressure; stopping the formation of the spray when the entire quantity of particles contained in the first compartment forms, as required, with the solvent, a suspension comprising between 80 and 99.9% solvent, if the solvent is introduced into the second compartment in liquid form, or a wet paste comprising between 1 and 10% solvent, if the solvent is introduced into the second compartment in gas form; recovering the suspension or wet paste formed.

Abstract: A method is followed to prepare a powder that includes carbon, silicon and boron, the silicon being in silicon carbide form and the boron being in boron carbide and/or free boron form. The method includes contacting a carbon-based precursor, a silicon-based precursor and a boron-based precursor BX3, X being a halogen atom, to obtain a mixture of these three precursors. The resulting mixture is subjected to laser pyrolysis. The boron-based precursor BX3 is heated, prior to the contacting step and/or simultaneously with the contacting step, to a temperature higher than the condensation temperature of the precursor.
