    摘要: A process for the “in situ” manufacture, in a pressurized CO2 medium, of coated particles. The manufacturing process is characterized in that the steps of synthesising the particles and of coating these particles are coupled in such a way that the synthesised particles remain dispersed in a pressurized CO2 medium at least until the coating. The device comprises a reactor for synthesising particles in a pressurized CO2 medium; a means of injecting the coating material or precursor thereof into said reactor; a means of supplying said reactor with a pressurized CO2 medium; in which the means of injecting the coating material or precursor thereof is coupled to the synthesis reactor in such a way that the injection of the coating material or precursor thereof into said reactor does not destroy the dispersion of the particles, in a pressurized CO2 medium, in said reactor.

    摘要: The present invention relates to a method of manufacturing a medium for microfiltration, for ultrafiltration, or for reverse osmosis, wherein hydrolysis is performed on an alkoxide, an organo-metallic compound, or a metal salt of an organic or an inorganic acid, optionally dissolved in an anhydrous organic solvent, in order to obtain a sol of particles of the oxide or of the hydroxide of the corresponding chemical element, a thickening agent is added to the sol, and the resulting sol is slip cast onto a support layer having pores which are larger than pores desired for the filter medium, the thin layer deposited on the support medium is then dried, and then heat treated to eliminate the thickening agent and to sinter the particles of the deposited thin layer. The thickening agent is added to the sol in conjunction with a strong acid whose anion does not form a complex with ions of the oxide or hydroxide metal, and the slip casting is performed by mere putting into contact without filtering.
