“…This excess oxygen degrades with cladding tubes. However, it is reported that some fluorite-type oxides with low O/M ratio, such as (U, Pu)O 2-x , are easily oxidized at even low temperatures such as 150 o C [1]. Oxidation of oxide fuels at low temperatures makes difficult in preparation and handling of the oxide fuels with low O/M ratio.…”

Two-step sintering with controlled oxygen partial pressure by using metallic buffer was applied to obtain dense non-stoichiometric CeO2-x. The samples prepared with single step sintering were cracked. The two-step sintering promoted almost full densification ≈ 98% in relative density without any cracks. Relative density of CeO2-x reached more than 98% of the theoretical density. The value of x in CeO2-x was obtained in the range of 1.68 in Mn/MnO to 1.98 in Co/CoO.
