Abstract :
High-energy ball milling process has been
applied to gadolinia-doped ceria system. The sinterability
of gadolinia-doped ceria was significantly
enhanced by the high-energy ball milling process. A
comparison was also made of the sintering behavior of
milled powders doped with gallia as a sintering aid.
Dense Ce0.8Gd0.2O1.9 ceramics with 97% of the theoretical
density could be obtained by sintering the milled
mixture with 0.5 mol% Ga2O3 addition at 1,250 C
for 5 h.
