摘要：

We report measurements of the heat capacity of the one-dimensional ionic conductor beta-eucryptite (LixAlxSi1-2xO4) over the temperature range 1.5-320 K. The entropy and enthalpy at 298.15 K were found to be Sdegrees(298.15) = (105.34+/-0.7) J/mol K and Hdegrees(298.15) = (21406.5+/-8) J/mol. The data are compared with specific heat results, reported in the literature for different temperature ranges. (C) 2002 Elsevier Science B.V. All rights reserved.
