摘要:
Process of restructuring a group of finely divided particles, of granulometries lower than 100 microns, wherein the particles to be restructured are placed in a bath of cryogenic liquid which is inert with respect to the particles, the operation of restructuring is allowed to proceed after which the cryogenic liquid is withdrawn for example by evaporation. Applications to the production of metallic alloys, special polymers, paints, inks, carbon black, special ceramics and pharmaceutical or food products.
