Abstract:
1. A facility for synthesizing silicon-containing nanoparticles by laser pyrolysis, including: a pyrolysis reactor; a first gas inlet of a precursor containing silicon; a second gas inlet of a carrier fluid; a third gas inlet linked to the first and second gas inlets, the third gas inlet feeding the pyrolysis reactor with a mixture of the carrier fluid and the precursor; a pulsed laser source having at least an adjusted power and an adjusted effective pulse duration in a laser firing period of said pulsed laser source; a regulating system comprising at least a first valve controlling a gas flow rate of the precursor at the first inlet and a second valve controlling a gas flow rate of the carrier fluid at the second inlet, said first and second valves being independently controllable and adjusting a rate of transit of the mixture into the reactor and a dilution of the precursor in the carrier fluid; and a recovery unit, for recovering silicon-containing nanoparticles at an outlet of the reactor.
