Abstract

Procedimento per la produzione di materiale in polvere a granulometria determinata e controllata con minimo scarto granulometrico consistente nel portare a fusione il materiale o la miscela di sostanze costituenti il materiale e nel disperderlo in forma di goccioline in un fluido, preferibilmente un fluido supercritico, il quale fluido sia privo di potere solvente per detto materiale e/o per dette sostanze, nel raffreddare la dispersione in modo da far solidificare dette goccioline, nel vaporizzare il fluido disperdente in modo che il materiale si depositi in forma di polvere fine e nel ricondensare e riutilizzare il fluido stesso. Impianto per la realizzazione del procedimento comprendente un reattore per la dispersione provvisto di precamera di mescolamento ed una camera di vaporizzazione del fluido e di raccolta del materiale in polvere.
