Summary
Sintering studies of CeO₂ and CeO₂ + 2 wt. % Ga₂O₃ were completed. Firing temperatures studied were 1250-1650 C with 2 to 4 hour firing soak times in air. Powders fabricated by three methods (as-received, attrition-mill and nitrite-derived) were studied. Attrition-milled CeO₂ improved densities as compared with as-received CeO₂. Attrition-milled CeO₂ with 2 wt.% Ga₂O₃ showed decreased densities with increasing temperatures. As-received CeO₂ with 2 wt.% Ga₂O₃ showed a opposite trend, increasing in density with increased firing temperature. Two pellet preparation methods were studied, a one-step-press method and a two-step-press method. The two-step-press method showed greater densities at lower firing temperatures and times as compared with the one-step-press method, however for CeO₂ + 2 wt.% Ga₂O₃, the two methods gave equivalent results at 1650 C, 6 hr. firing conditions.
