Abstract

Procedimiento cerámico de sinterización para producir cuerpos sinterizados densos de composiciones conteniendo óxido de uranio, caracterizado por comprender las etapas de sinterizar cuerpos, hechos compactos, de los polvos conteniendo óxido de uranio, a una temperatura en el alcanoe desde alrededor de 900 a 1500ºC, en una atmósfera sinterizadora, que comprende una mezcla de dióxido de carbono e hidrógeno, y enfriando el cuerpo sinterizado en una atmósfera, seleocionada entre el grupo consistente en hidrógeno seco, hidrógeno húmedo y una mezcla de hidrógeno y dióxido de carbono.
