    The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium which has been combined with fluorine to form uranium hexafluoride (UF 6) gas through a porous membrane (barrier) and using the different molecular velocities of the two isotopes to achieve separation.

  • Three Important Methods of Separating IsotopesGulpMatrix

    Separating Isotopes is a chemical process that is hinged on the difference in mass of these isotopes. As isotopes have the same chemical properties their separation must depend on physical methods making use of the slight mass difference between different isotopes.The following underlisted methods are the most important.
