Abstract (en)
Method of restructuring a group of fine particles of particle sizes smaller than 100 microns, characterised in that the said particles to be restructured are placed in a cryogenic liquid bath which is inert towards the said particles, the restructuring operation proper is ensured, after which the cryogenic liquid is withdrawn, for example by evaporation. <??>Applications to the production of metal alloys, of special polymers, of paints, of inks, of carbon black, of special ceramics and of pharmaceutical or alimentary products.
