Claim 1
Independent Claim
83 words
A PROCESS OF PREPARING A STABLE SLURRY OF THE OXIDE OF AN ACTINIDE ELEMENT, COMPRISING DISSOLVING THE NITRATE OF SAID ACTINIDE ELEMENT IN A COMBUSTIBLE ORGANIC SOLVENT, CONVERTING THE SOLUTION OBTAINED INTO A SPRAY, IGNITING THE SPRAY WHEREBY AN OXIDE POWDER IS OBTAINED, SLURRYING SAID OXIDE POWDER IN AN AQUEOUS SOLUTION OF A SUBSTANCE WHICH IS ADSORBABLE BY SAID OXIDES, DISPERSING THE SLURRY IN A COLLOID MILL WHEREBY A SUSPENSION IS OBTAINED, AND ELECTRODIALYZING SAID SUSPENSION UNTIL A LOW SPECIFIC CONDUCTANCE IS REACHED.
