Claim 1
Independent Claim
94 words
A PROCESS FOR PREPARING STABLE URANOUS OXIDE SOLS MADE UP OF AQUEOUS DISPERSIONS OF URANOUS OXIDE PARTICLES IN THE SIZE RANGE OF 10 TO 300 MILLIMICRONS WHICH COMPRISES PREPARING A SOLUTION OF A NON-OXIDIZING URANYL SALT SELECTED FROM THE GROUP CONSISTING OF THE OXYBROMIDE, THE OXYCHLORIDE, OXYACETATE AND THE OXYFORMATE, ELECTRODIALYZING TO CONVERT THE NON-OXIDIZING URANYL SALT, AUTOCLAVING THE URANOUS OXYSALT SOLUTION AT A TEMPERATURE OF ABOUT 100 TO 200*C. FOR A PERIOD OF TIME SUFFICIENT TO COMPLETE SOL PARTICLE PREPARATION, REDISPERSING IN DEIONIZED WATER AND RECOVERING URANOUS OXIDE SOL AS THE FINAL PRODUCT.
