Elastic Constants, Bulk Modulus, and Compressibility of H2O Ice Ih for the Temperature Range 50 K-273 K

摘要

Published elastic constant data for H2O ice in the Ih phase are compiled and evaluated. Fits of the five elastic constants for 50 = T/K = 273 are conducted to yield a reliable and convenient source for elastic constant values. Various elastic properties can be calculated from the elastic constants obtained herein. The elastic constants are used to determine the adiabatic bulk modulus B-S for the same temperature range with an estimated uncertainty of less than 1.3%. Fitting those data yields an equation for B-S that is extrapolated to provide values for 0 = T/K = 50. The adiabatic compressibility K-S, isothermal bulk modulus B-T, and isothermal compressibility K-T are calculated from B-S. Comparisons are made to published data.
