Abstract
La presente invención se refiere a método de producción de una estructura cerámica autoportante, CARACTERIZADO porque comprende los pasos de: (a) proveer un primer cuerpo cerámico autoportante que comprende (i) un primer producto de reacción de oxidación policristalino formado al oxidarse un primer metal madre en función con un primer oxidante, y (ii) porisidad interconectada por lo menos parciamente accesible desde una o mássuperficies de dicho cuerpo cerámico; (b) orientar un cuerpo del segundo metal madre y dicho primer cuerpo cerámico en relación uno con el otro de modo que la funsión y la reacción de oxidación de dicho segundo metal madre con un segundo oxidante en fase vapor causará la formación de un segundo producto de reacción de oxidación policristalino en dirección de, y dentro de, dicha porosidad interconectada de dicho primer cuerpo cerámico; y (c) celantar dicho segundo metal madre a un margen de temperatura por sobre su punto de funsión pero por debajo de los puntos de funsión de los productos de reacción de oxidación primero y segundo para formar un cuerpo de segundo metal madre en funsión y, dentro de dicho margen de temperatura, (i) hacer reaccionar dicho cuerpo de segundo de segundo metal madre en funsión con dicho oxidante en fase vapor para formar dicho segundo material policristalino de producto de racción de oxidación: (ii) mantener al menos una porción de dicho segundo producto de reacción de oxidación en contacto con y entre, dicho cuerpo de segundo metal madre en funsión y dicho oxidante, por lo cual el segundo metal es atraído a través de dico segundo material policristalino hacia el oxidate de modo que continúa formándose el segundo producto de reacción de oxidación en la interfase entre el oxidante y el producto de reacción de oxidación segundo previamente formado, y (iii) continuar dicha reacción durante un tiempo suficiente para infiltrar por lo menos parte de dicha porossidad de dicho primer cuerpo cerámico con dicho segundo material policristalino.
