| Abstract: | Based on the study on ionic structure of cryolite melt, changes of the diffusivities of Na+ and F- ions in cryolite melt with its molecular ratio were calculated using the cathodic overvoltage data in electrolysis process and both ionic mobilities. The diffusivities calculated show a satisfactory agreement with those measured. |
