948,948. Plutonium dioxide; nuclear fuel. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 19,1962 [ April 27, 1961], No. 15371/61. Headings G6C and G6R. A dense sintered body containing plutonium dioxide is made by forming a compacted body comprising plutonium dioxide powder and from 0.05 - 2% by weight (based on the PuO 2 ) of iron in the form of the oxide and sintering by heating in an oxidising atmosphere, e.g. air. The iron may be added in the form of an aqueous solution of ferric nitrate or as finely divided metallic iron. Sintering temperatures are from 1400‹ - 1650‹C. The sintered body has a density of up to 11. 0 gms. per cc. Reference is made to the production of sintered mixtures of PuO 2 with other actinide oxides, e.g. UO 2 .
