Abstract
Un procedimiento continuo para la fabricacion de partículas solidas de persales de metal alcalino por reaccion de una solucion acuosa de peroxido de hidrogeno con una solucion acuosa de una sal de metal alcalino y cristalizacion de la persal formada en un cristalizador clasificador que comprende una zona agitada de formacion y de crecimiento de los cristales de persal, una zona no agitada de clarificacion de la solucion y una zona de clasificacion por elutriacion en una corriente líquida extraída en la zona de clarificacion de las partículas obtenidas. También se describe una instalacion para fabricar dichas partículas.
