Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
99 words
IN A PROCESS FOR SEPARATING URANIUM FORM A URANIUMZIRCONIUM METALLIC MASS IN WHICH THE INITIAL STEPS COMPRISES CONTACTING SAID COMPOSITION WITH ANHYDROUS HYDROGEN CHLORIDE IN A REACTION ZONE AT A TEMPERATURE IN THE RANGE 350*C. TO 800*C. TO FORM VOLATILE ZIRCONIUM TERTRACHLORIDE AND A URANIUM-CONTAINING NITRIC ACID INSOLLUBLE HYDROCHLORINATION RESIDUE AND WHEREIN SAID ZIRCONIUM TETRACHLORIDE IS REMOVED FROM SAID REACTION ZONE, THE IMPROVEMENT WHICH COMPRISES CONTACTING SAID NITRIC ACID INSOLUBLE HYDROCHLORINATION RESIDU WITH GASEOUS CARBONTETRACHLORIDE AT A TEMPERATURE WITH THE RANG 550* C. TO 600*C. TO FORM A URNAIUM CHLORIDE VAPOR, AND THEREAFTER CONDENSING SAID VAPOR INA CONDENSATION ZONE.
