Abstract

PROCEDIMIENTO PARA PREPARAR POLVO DE TANTALO EN ESCAMAS, CUYO POLVO TIENE UNA DENSIDAD SCOTT SUPERIOR A 1,097 G/CC APROXIMADAMENTE Y PREFERIBLEMENTE AL MENOS EL 90% APROXIMADAMENTE DE LAS PARTICULAS EN ESCAMAS NO TIENEN DIMENSION ALGUNA SUPERIOR A 55 MICRAS APROXIMADAMENTE. LOS AGLOMERADOS DEL POLVO DE TANTALO EN ESCAMAS PROPORCIONAN CARACTERISTICAS MEJORADAS DE CAPACIDAD DE FLUJO, RESISTENCIA EN BRUTO Y PRENSADO, EN COMPARACION CON LOS POLVOS DE TANTALO EN ESCAMAS CONVENCIONALES. EL PROCEDIMIENTO COMPRENDE PREPARAR TANTALO EN ESCAMAS Y REDUCIR ENTONCES EL TAMAÑO DE LAS ESCAMAS HASTA CONSEGUIR UNA DENSIDAD SCOTT SUPERIOR A 1,097 G/CC APROXIMADAMENTE. LA INVENCION PROPORCIONA TAMBIEN PELLETS Y CAPACITORES PREPARADOS A PARTIR DEL REFERIDO POLVO DE TANTALO EN ESCAMAS.
