Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE METALES DE ELEVADA PUREZA A PARTIR DE SUS HALOGENUROS, MEDIANTE LA REDUCCION DE ESTOS CON METALES EN FASE VAPOR.COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE MEZCLAN LOS VAPORES DE UN METAL REDUCTOR CON UN HALOGENURO DEL METAL DESEADO, FUERA O DENTRO DE LA ZONA DE REACCION PRIMARIA; SEGUNDA, SE EFECTUA LA REACCION EN LA ZONA DE REACCION PRIMARIA, A UNA TEMPERATURA SUPERIOR A LOS 500 GRADOS E INFERIOR A LA TEMPERATURA DE SOLIDIFICACION DEL METAL DESEADO; TERCERA, SE COMPLETA LA REACCION EN UNA ZONA DE REACCION EN FORMA DE CICLON; Y POR ULTIMO, SE SEPARA EL METAL EN FORMA DE POLVO Y SE RECUPERAN LOS HALOGENUROS DEL METAL REDUCTOR.
