| Abstract: | TG, DSC and X-ray measurements were made to characterize the water absorption process by Li (50%) — Na (50%)β-alumina. The equilibrium water content, dehydration enthalpies and lattice parameter values have been determined and compared with those previously obtained for pure Li and Naβ-aluminas. The mixedβ-alumina is shown to be very similar to Liβ-alumina as concerns the dehydration enthalpy and the temperature range in which the dehydration occurs, while it seems to be very similar to Naβ-alumina with respect to the equilibrium water content andc-axis values. |
