Abstract
La presente invención se refiere a método para producir cuerpos de estructura cerámica autoportante que consiste esencialmente en (1) alúmina como el producto de reacción de oxidación de un metal madre de aluminio y un oxidante en fase vapor que contiene oxígeno gaseoso, y optativamente (2) constituyentes metálicos no oxidados, y constituida por una microestructura refinada atribuible a la adición de uno o más modificadores de procesamiento en relación a sustancialmente el mismo producto de reacción de oxidación sin un modificadxor de procesamiento, CARACTERIZADO porque comprende los pasos de: (A) proveer uno o más de dicho modificadores de procesamiento, o una fuente de los mismos, (B) usando dicho(s) modificador(es) en conjunto con dicho metal madre, (C) calentar dicho metal madre en presencia de dicho oxidante en fase vapor a ua temperatura por sobre su punto de fusión pero debajo del punto de fusión de dicho producto de reacción de oxidación para formar un cuerpo de metal en fusión y a dicha temperatura hacer reaccionar dicho metal en fusión con dicho oxidante en fase vapor para formar un producto de reacción de oxidación, producto que está en contacto con, y se extiende entre, dicho cuerpo de metal en fusión y dicho oxidante en fase vapor, y a dicha temperatura transportar dicho metal en fusión a través de dicho producto de reacción de oxidación hacia dicho oxidante en fase vapor de modo que el producto de reacción de oxidación continúa formándose en la interfase entre dicho oxidante en fase vapor y el producto de reacción previamente formado, formando con esto un cuerpo progresivamente más grueso de dicho producto de reacción de oxidación y continuar dicha reacción durante un tiempo suficiente para producir dicho cuerpo que tiene dicha microestructura refinada y (D) recuperar dicho cuerpo.
