Abstract
PROCEDIMIENTO PARA LA PURIFICACION DE LITIO. CONSISTE EN AGITAR EL BAÑO CONSTITUIDO POR EL LITIO FUNDIDO BAJO ATMOSFERA INERTE; EN EVAPORAR SELECTIVAMENTE LAS IMPUREZAS A UNA TEMPERATURA COMPRENDIDA ENTRE 400 Y 700 GRADOS BAJO UNA PRESION INFERIOR A 10 PASCAL; Y EN CONDENSAR LAS IMPUREZAS EVAPORADAS A UNA TEMPERATURA INFERIOR A 100 GRADOS. EL DISPOSITIVO UTILIZADO CONSTA DE UN RECINTO ESTANCO FORMADO POR UNA PARTE ALTA (1) QUE ESTA EQUIPADA CON UN CONTENEDOR (9) EN EL CUAL EL LITIO FUNDIDO ES AGITADO Y DEL CUAL SE EVAPORAN LAS IMPUREZAS, Y POR UNA PARTE BAJA (13) REFRIGERADA, LA CUAL ESTA EQUIPADA CON UNA SUPERFICIE DE CONDENSACION (17) Y CON UNA TUBERIA (16) DE PUESTA BAJO DEPRESION. DE APLICACION EN LA INDUSTRIA AERONAUTICA.
