摘要： The invention relates to a method for preparing mineral particles (p) from mineral particle precursors, said method comprising a step (E) that comprises injecting a fluid medium (F) containing said precursors in solution and/or dispersed in a solvent in a reactor containing CO2 at a supercritical state using an injection nozzle giving into an area where the supercritical CO2 is at a temperature higher than or equal to the conversion temperature of the precursors into corresponding mineral species, the invention also relates to particles (p) obtained according to the method and to the use thereof.

摘要： The subject of the present invention is a method for producing a gas separation membrane, comprising the deposition of a film from a silica sol onto a porous support followed by heat treatment of the film thus deposited, in which the silica sol deposited is prepared by hydrolysing a silicon alkoxide in the presence of a doping amount of a precursor of an oxide of a trivalent element, especially boron or aluminium. The invention also relates to the membranes as obtained by this method, and also to their uses, especially for the separation of helium or hydrogen at high temperature, and in particular for removing impurities in helium streams.
