US 2010/0059360 A1 · Method For The Production Of Nanoparticles

Abstract

The present invention relates to methods for the production of nanoparticles which may be optionally coated. In particular, the present invention relates to methods for the production of nanoparticles characterized in that precursors are subjected to substantially the same amount of activation energy or combination of activation energies in the activation zone at a predetermined concentration of precursors and at a predetermined time of exposure to the activation energy/energies. Furthermore, the present invention relates to nanoparticles produced by the methods according to the present invention. Finally, the present invention concerns a device for producing nanoparticles according to the method of the present invention. The invention provides for a tighter particle size distribution of the generated nanoparticles. The activation energy is selected from the group of RF, MW, IR, plasma, heat and photon absorption.

Dependent claims

A method for preparing nanoparticles having a narrow size distribution comprising the steps of:

flowing precursors through an activation zone of a reactor or moving a unit which provides activation energy to said activation zone of said reactor;
and
activating said precursors in said activation zone of said reactor with an amount of an activation energy for a predetermined time at a predetermined concentration of the precursors, wherein amount of activation energy over the predetermined time when said precursors pass through the activation zone is substantially the same for all of the precursors, said activating step forming nanoparticles from said precursors.
