Isotope Separation by Thermal Diffusion in Ternary Systems

Abstract

The problem of isotope enrichment of the middle component in ternary systems via thermal diffusion is discussed, emphasis being placed on systems where the initial concentration of the middle component is considerably less than that of either end component. The design and operation of a 12‐column thermal diffusion apparatus in which 99.99% Ne²², 99.4% Ar³⁶, and 8.0% Ar³⁸ isotopic samples were produced is described. The concentration of the midcomponent as a function of an end concentration is found to be adequately described by the Jones—Furry theory. The experimental results suggest suitable techniques for application in similar isotopic enrichment programs.
