Abstract

En fremgangsmåte for restrukturering av en gruppe findelte partikler med granulometrier under 100 |m omfatter at partiklene, som skal restruktureres, anbringes i et bad av kryogen væske, som er inert overfor partiklene idet struktureringsoperasjonen i og for seg tillates å skje, hvoretter den kroyogene væske trekkes av f.eks. ved fordamping.Oppfinnelsens fremgangsmåte benyttes for fremstilling av metalliske legeringer, spesielle polymerer, maling, sværter, sot, spesielle keramiske og farmasøytiske produkter eller næringsmiddelprodukter.
