SINTERING OF THORIUM AND THORIA

Technical Report ·
OSTI ID:4286723
Whereas the results previously published suggest that calcium-reduced thorium powder with a high green density cannot be sintered satisfactorily, the present work indicates that it is possible to do so and reach a high density (11.26) in the sintered product. The effect of such variables as bulk density of the powder and its particle size, compacting pressure, temperature, and time of sintering on the sintering characteristics has been studied. High-density thoria can be obtained either by hot pressing at temperatures above 17O0 deg C or by cold compacting and sintering with the help of additives. It was thought that the use of high sintering temperature could be avoided by employing activated thoria. Accordingly activation was done both in air and in hydrogen at various temperatures and sintering done in air and under vacuum up to 1500 deg C, and the results of these experiments are presented.
