Claim 1
Independent Claim
82 words
THE METHOD OF PREPARING PLUTONIUM-CONTAINING THORIUM OXIDE PARTICLES WHICH COMPRISES ADDING PLUTONYL NITRATE IN AN AQUEOUS SUSPENSION OF DISPERSIBLE THORIUM OXIDE AT A PLUTONIUM PROPORTION UP TO ABOUT 5 MOLE PERCENT OF THE TOTAL METAL, ADJUSTING THE RESULTING MIXTURE OF A PH OF 2.5 TO 4.0, DIGESTING THE RESULTING MIXTURE UNTIL A SOL IS FORMED, EVAPORTING SAID SOL AT A TEMPERATURE BELOW 100*C. WHEREBY DRIED GEL FRAGMENTS ARE FORMED AND FIRING THE RESULTING GEL FRAGMENTS AT A TEMPERATURE OF AT LEAST 1100*C.
