THE METHOD OF PREPARING HIGH-DENSITY MILLIMETERSIZE UO2 PARTICLES WHICH COMPRISES PRECIPITATING COLLOIDAL HYDROUS URANOUS OXIDE IN AQUEOUS SOLUTION UNDER A NONOXIDIZING ATMOSPHERE, SEPARATING THE RESULTING PRECIPITATE FROM THE REMAINING SOLUTION, WASHING SAID PRECIPITATE UNDER A NON-OXIDIZING ATMOSPHERE, HEATING SAID PRECIPITATE TO DRYNESS UNDER A NON-OXIDIZING ATMOSPHERE AT A TEMPERATURE BELOW ABOUT 130*C., SAID TEMPERATURE BEING MAINTAINED BELOW 100*C. UNTIL SAID PRECIPITATE HAS PASSED THROUGH A PASTY STAGE, AND FIRING THE RESULTING FRAGMENTS AT A TEMPERATURE OF AT LEAST 1050*C. IN A NON-OXIDIZING ATMOSPHERE.
