METHOD OF PRODUCTION OF HIGHLY ENRICHED ISOTOPES OF VANADIUM Russian patent published in 2004 - IPC

FIELD: physical researches. SUBSTANCE: the invention may be used at realization of physical researches. Vanadium oxychloride is produced from a compound with concentration of a chlorine 35 isotope of no less than 85 %. For production of an increased concentration of a chlorine - 35 isotope it is possible to use a two-phase physicochemical method of separation with the help of apparatuses of a column type or a centrifugal type. Produced vanadium oxychloride having the form of a gaseous mixture of isotopes is fed into a cascade of gaseous centrifugal machines. Separation is carried out by a method of centrifugation. As the result they produce vanadium isotopes with concentration of isotope V50 equal to 94.37 % and 98.4 %. The invention allows to produce highly enriched vanadium isotopes at high productivity and low power consumption. EFFECT: production of highly enriched vanadium isotopes at high productivity and low power consumption. 2 cl, 1 tbl, 4 dwg
