Abstract
La presente tiene por objeto un procesamiento de fabricación de una pieza maciza, destinada a formar todo o parte de un ánodo para la producción de aluminio por electrólisis ígnea, y que contiene un cermet formado de por lo menos un óxido metálico, tal como un óxido mixto con estructura de espinela, y de por lo menos una fase metálica, en el que se utiliza un óxido mixto que comprende un metal R en forma de cationes en su estructura química, el susodicho metal R es susceptible de reducirse en todo o parte mediante una operación de reducción, durante el procedimiento de fabricación, para formar todo o parte de la susodicha fase metálica. Este procedimiento permite obtener un cermet cuya fase metálica comprende una distribución homogénea de finas partículas metálicas.
