Abstract or Summary
  • The chemically similar elements hafnium and zirconium occur together in nature. Because of their very dissimilar nuclear properties it is of commercial importance to separate them for use in the atomic energy field. One or more of the steps in the separation and purification processes presently used involve the volatile hafnium and zirconium tetrachlorides. It would be economically beneficial if a separation could be made by fractional sublimation of these tetrachlorides. An experimental technique for determining solid-vapor equilibria of the hafnium tetrachloride-zirconium tetrachloride system was used to obtain basic data for such a fractionating system. Vapor and solid phases of the mixed tetrachlorides were brought to equilibrium at 315°C, separated and analyzed. Complete vaporization and recondensation of the solid assured equilibrium in this phase. The data obtained, although somewhat scattered, followed a Raoult's law-type relationship in which the concentration of a component in the vapor phase is equal to the product of its mole fraction in the solid phase and its vapor pressure as a pure solid at the temperature considered.
