Abstract (en)
[origin: WO2010125149A1] The invention relates to a method for producing a powder including carbon, silicon and boron, the silicon being in the form of silicon carbide and the boron being in the form of boron carbide and/or free boron, including the following steps: a step of placing in contact a carbon-based precursor, a silicon-based precursor and a boron-based precursor BX3, where X is a halogen atom, such as to obtain a mix of said three precursors; a step of subjecting the resulting mixture to laser pyrolysis, the boron-based precursor BX3 being heated, prior to the step of placing in contact and/or simultaneously with the step of placing in contact, to a temperature higher than the condensation temperature of said precursor.
