Abstract
La presente invención se refiere a un método para producir una estructura cerámica autoportante que comprende un material policristalino comprendido de una primera región y una región terminal integral con dicha primera región pero diferentes de la misma en la composición o la macroestructura o ambas, comprendiendo el método los pasos de: a) calentar dicho metal madre a un margen de temperatura por sobre su punto de fusión pero debajo del punto de fusión del producto de reacción de oxidación para formar un cuerpo de metal madre en fusión y b) demntro de dicho margen de temperatura, (i) hacer reaccionar dicho cuerpo del metal madre en fusión con un oxidante para formar dicho producto de reacción de oxidación, (ii) mantener inicialmente por lo menos una posición de dicho producto de reacción de oxidación en contacto con, y entre, dicho cuerpo de metal madre en fusión y dicho oxidante, para transportar progresivamente metal madre en fusión desde dichos cuerpos a través del producto de reacción y hacia el oxidante, de modo que el producto de reacción de oxidación continúa formándose en la inter fase entre el oxidante y el producto de reacción de oxidación formando previamente, formando con ésto una primera región progresivamente más gruesa de producto de reacción de oxidación que contiene inicialmente metal madre interconectado c) atenuar dicho transporte de metal madre en fusión desde dicho cuerpo d) después del paso (c), continuar dicha reacción dentro de dicho margen de temperatura durante un tiempo suficiente para transportar dicho metal madre en fusión interconectado desde dicha primera región hacia una superficie de dicha primera región para formar producto en reacción de oxidación sobre dicha superficie como dicha región terminal.
