| Abstract: | An analysis of the Grűneisen parameter and its
volume derivatives has been presented using the generalized free-volume theory
for materials at extreme compression. It has been re-established using a direct
and simple method that the Slater’s formula for the Grűneisen parameter has the
status of an identity at infinite pressure as found earlier by Stacey and Davis
(Phys Earth Planet Inter, 142 (2004)
137). The expressions based on the free-volume theory extrapolated to infinite
pressure are found to be in agreement with the corresponding expressions for
higher-order Grűneisen parameters obtained recently by Shanker et al. (Physica B, 404 (2009) 4083). |
