AbstractSelf-diffusion coefficients of 7Li+ ions have been measured in molten LiNO3 with several compositions of 6Li+ and 7Li+ over a temperature range from 537 to 615 K. The NMR spin-echo method with pulsed field gradients was applied. It was found that the self-diffusion coefficient depends on the isotopic composition and shows a maximum at equimolar ratio. At temperatures above 600 K this behaviour disappears.

The electrical conductance and its temperature dependence of molten lithium chlorate have been determined. Similar results have been obtained for lithium chlorate melts containing small quantities of methyl alcohol, propyl alcohol, lithium nitrate, lithium hydroxide, and water.The results obtained, taken in conjunction with the results of previous work, all indicate that the melt is complex. There is probably considerable association and this is especially evident slightly above the melting point: at temperatures in this region the temperature change of the properties of the lithium chlorate melt is greatest.The activation energy of conductance is approximately the same as the activation energy of viscous flow, for pure lithium chlorate melt and for mixtures of lithium chlorate with lithium nitrate. From this it appears that the melt constituents are not principally the simple ions, but that some form of cohesion exists between the simple constituents of the melt.The addition of water to the lithium chlorate melt causes the melt properties to alter considerably, especially the transport properties, viscosity and conductance. It is suggested that these changes may in part be due to a breakup of the structural entities of the pure melt, though the increase in electrical conductance cannot be completely explained in this way. A cryoscopic investigation seems to indicate that water is •not present as such in the melt.
