Abstract

Procedimento continuo per la fabbricazione di particelle solide di persali di un metallo alcalino rivestite mediante cristallizzazione di una soluzione acquosa sovrasatura di persali e rivestimento delle particelle di persali in un tino di post - cristallizzazione nel quale si introduce almeno un agente di rivestimento e si realizza una cristallizzazione dell'agente di rivestimento attorno alle particelle di persali in condizioni regolate di temperatura e di agitazione.
