ABSTRACT:
The materials to be sintered are placed in a deformable container which is in turn placed within a non-deformable treatment module equipped with heating means. The temperature of the container is increased under constant pressure until commencement of sintering. The temperature and pressure of the materials are increased simultaneously until sintering conditions are achieved, then maintained at a level stage for a predetermined period of time. The pressure is then reduced to the normal value while maintaining the temperature. The temperature is finally reduced to the room-temperature value.
