Statistical Inference Second Edition

Low-nitrate plutonia sols having a NO3/Pu mole ratio in the range 0.1 to 0.4 with an average crystallite diameter of 30 to 80 A can be produced when a sol is prepared by solvent extraction of a plutonium nitrate seeded with a plutonia sol. When the seeded sol is taken to dryness and heated for 10 to 120 minutes at a temperature in the range 180 DEG -230 DEG C. in a dry sweep gas, nitrate removal occurs and the baked solid can easily be dispersed to form a stable sol.
