Abstract (en)

[origin: CA2652005A1] The present invention relates to a method for the ~in situ~ manufacture, in a pressurised CO2 environment, of coated particles. The manufacturing met hod is characterised in that the steps of synthesising the particles and coa ting these particles are coupled so that the synthesised particles remain di spersed in a pressurised CO2 environment at least until the coating. The dev ice comprises a reactor for synthesising particles in a pressurised CO2 envi ronment; a means of injecting the coating material and its precursor into sa id reactor; a means of feeding said reactor with a pressurised CO2 environme nt, in which the means of injecting the coating material or its precursor is coupled to the synthesis reactor so that the injection of the coating mater ial or its precursor into said reactor does not suppress the dispersion in t he pressurised CO2 environment of the particles in said reactor.
