• Bennema's theory of crystal growth from a solution was modified and used in explaining fractionations of tritiated water in the crystal-growth processes of several inorganic hydrated salts from concentrated aqueous solutions. It was suggested that some water molecules in the aqueous solutions were free to become growth units which are not necessarily activated for entering the crystal surface. The dilution of tritiated water in the crystal was observed; this was explained in a satisfactory way in terms of the surface-diffusion model originally proposed by Burton, Cabrera, and Frank. On the contrary, the volume diffusion model was inadequate for interpreting the fractionation of tritium.
