The sintering behaviour of ceria pellets was studied to produce dense, sound and crack-free pellets. Ceria is prepared by the precipitation of ammonium cerous carbonate (ACeC). The precipitate of ACeC is dried and then calcined to produce ceria (CeO2) powder. The ceria powder is used to fabricate pellets which are sintered at 1200...1500 °C. It was found that higher density (more than 85 % of the theoretical), sound and crack-free ceria pellets can be obtained via calcination of ACeC powders at 600 °C for 2 h, pressing the obtained ceria powders into pellets at 550 N/mm2, and then sintering these pellets at 1500 °C for 3 h in air. powder metall. int. 21(1989) [1]
