Abstract
Un material adecuado para su utilización como superficie de ánodo activo en la reducción electrolítica de alúmina en metal de aluminio definido por la fórmula: A1+xB1+deltaCdO4, en la cual: A es un catión divalente de una mezcla de cationes y con una relativa preferencia por la coordinación octahédrica; B es un catión trivalente o mezclas de cationes con una relativa preferencia por la coordinación tetrahédrica; C es un catión trivalente o una mezcla de cationes con una relativa preferencia por la coordinación octahédrica o un catión cuatro-valente o mezcla de cationes con una relativa preferencia por la coordinación octahédrica; O es el elemento oxígeno. Cuando C es trivalente x = 0; 0,8 < d < 1; delta < 0,2 y x + d + delta es esencialmente igual a 1. Cuando C es tetra-valente 0,4 < x < 0,6; 0,4 < d < 0,6; delta < 0,2 y x + d + delta es esencialmente igual a 1.
