摘要： A METHOD IS DISCLOSED OF PREPARING SPHERICAL PARTICLES OF ACTINIDE HYDROXIDE GEL, WHICH PARTICLES CAN BE CONVERTED BY THERMAL TREATMENT INTO SPHERICAL OXIDE, AND IF CARBON HAS BEEN INCORPORATED INTO THE GEL, CARBIDE PARTICLES. SPHERICAL ACTINIDE OXIDE AND CARBIDE PARTICLES ARE NEEDED IN NUCLEAR TECHNICS. AN ACTINIDE HYDROXIDE SOL IS MIXED WITH A SOLUTION OF ONE OR MORE AMMONIUM DONORS AND SUBSEQUENTLY GELLED BY DISPERSION INTO A HOT LIQUID NONMISCIBLE WITH WATER.

摘要： CONCENTRATED ANION-DEFICIENT SALT SOLUTIONS ARE PREPARED OF THE ACTINIDE OXIDES PUO2, UO2, UO3 ANDU3O8 BY DISSOLVING ONE OR MORE OXIDES IN AN AQUEOUS SOLUTION OF THORIUM NITRATE AT A CONCENTRATION OF 4 MOLAR OR GREATER AND AT A TEMPERATURE OF 60* C. OR MORE. ANION-DEFICIENT SALT SOLUTIONS OF ACTINIDE METALS SO PRODUCED ARE USEFUL AS STARTING MATERIALS FOR THE MANUFACTURE OF CERAMIC NUCLEAR FUEL PARTICLES BY THE SOL-GEL PROCESS.
