Abstract
La presente invención se refiere a método para producir un material de alúmina de alta pureza que consiste esencialmente en el producto de reacción de oxidación de un metal madre de aluminio y un oxidante en fase vapor que contiene oxígeno, teniendo material de aluminio de una pureza no inferior a 99.9 por ciento ponderal de alúmina, CARACTERIZADO porque dicho método comprende los pasos de: (A) calentar dicho metal madre de aluminio a una temperatura por sobre el punto de fusión de dicho metal madre de aluminio pero debajo del punto de fusión de dicho producto de reacción de oxidación para formar un cuerpo de metal madre de aluminio en fusión, y a dicha temperatura hacer reaccionar dicho cuerpo de metal madre de aluminio en fusión con dicho oxidante en fase vapor que contiene oxígeno para formar alúmina como dicho producto de reacción de oxidación; mantener al menos una porción de dicho producto de reacción de oxidación en contacto con, y entre, dicho cuerpo de metal madre de aluminio en fusión y dicho oxidante en fase vapor que contiene oxígeno para atraer metal madre de aluminio en fusión a través del producto de reacción de oxidación hacia dicho oxidante en fase vapor que contiene oxígeno de modo que el producto de reacción de oxidación continúa formándose en la interfaz entre el oxidante en fase vapor que contiene oxígeno y el producto de reacción de oxidación formado previamente, y continuamente dicha reacción durante un tiempo suficiente para producir un cuerpo de cerámica que comprende alúmina y constituyentes metálicos, y (B) triturar dicho cuerpo de cerámica, y (C) proveer uno o más lixiviadores y poner en contacto dicho material triturado con dichos lixiviadores durante un tiempo suficiente para eliminar o disolver materiales que no son de alúmina a partir de dicha alúmina, y (D) recuperar dicho material de alúmina sustancialmente puro.
