Abstract

TRATAMIENTO QUE FACILITA LA FLUIDIFICACION DE LOS POLVOS FINOS DESTINADOS A LA COMPACTACION, POR EJEMPLO, PARA FABRICAR ANODOS DE CONDESADORES ELECTROLITICOS. EL POLVO FINO SE MEZCLA CON POLVO BASTO ADICIONAL, EN PROPORCION NO MAYOR DE CUATRO A UNO EN PESO, ANTES DE INTRODUCIRLO EN LA CAMARA DE FLUIDIFICACION Y RECUBRIENDOSE POSTERIOMENTE POR UNA REACCION DE FASE DE VAPOR HETEROGENEA. EL TAMAÑO DE LAS PARTICULAS DE METAL FINO ES MENOR DE 10 MICRAS Y EL RECUBRIMIENTO FINAL PUEDE SER UN CATALIZADOR O UN METAL VALVULA.
