Abstract

Procedimiento de preparación de objetos con forma, de siliciuros de uranio, caracterizado porque consiste en introducir en un molde una mezcla íntima de partículas de uranio y de silicio en proporción correspondiente al siliciuro de uranio que se desea obtener, en calentar, en una primera fase, esta mezcla en vacío en su molde a una temperatura por lo menos igual a 450 grados C. e inferior a su temperatura de fusión para hacer reaccionar el silicio y el uranio, y luego en someter, en una segunda fase, el producto coherente poroso obtenido, a un caldeo en vacío a una temperatura superior a la del primer caldeo para hacer completa la reacción entre el silicio y el uranio y para obtener un producto coherente no poroso.
