Abstract

Procedimiento para fabricar bolas de aluminio a partir de un sol de alúmina, caracterizado porque se mezclan soluciones de sol de alúmina y de hexametilentetramina a una temperatura inferior a la. temperatura de gelificación, se dispersa esta mezcla en forma de gotitas en un líquido muy poco miscible con agua, a una temperatura comprendida entre 50 y 105ºC, se procede, en un líquido muy poco miscible con agua, a un envejecimiento de las bolas formadas, a una temperatura superior a 105ºC y a una presión superior a la presión atmosférica, se efectúa luego un envejecimiento de las bolas en medio básico, y se lava, seca y calcina las bolas resultantes.
