Abstract

We have measured the volume and electrical conductance of a range of LiC1 and LiI solutions from dilute to saturation concentration, from 20°C to 150°C and up to 5kbar. The data have been converted to molar conductivities and fitted to the V.T.F. equation to obtain the "ideal glass transition" temperature.({up harpoon right}p/{up harpoon right}1) passes through a maximum with increasing pressure and this is reflected by To which also passes through a minimum. The maximum in ({up harpoon right}p/{up harpoon right}1) diminishes with increasing concentration whilst To, which is initially concentration dependent, increases with ionic charge density. Both phenomena reflect the transition from dilute solution to molten salt like conductance characteristics.
