Chemical aspects of the preparation of stable and radioactive isotopes

The requirements to the element chemical form at various stages of the isotope separation process thorough the centrifugal technology are briefly considered. The brief review of the results of the studies on the stable and radioactive isotopes separation with application of chemical operations providing for the substance necessary form, i.e. volatile compounds with the vapour elasticity not less than 5 mm Hg at the common temperature for the stage of the isotope separation and nonvolatile stable compounds as the finite products is presented. The perspective studies in the area of the rare earth elements isotope separation are indicated
