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 (<i style="mso-bidi-font-style:normal">Phys Earth Planet Inter</i>, 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 <i style="mso-bidi-font-style:normal">et al</i>. (<i style="mso-bidi-font-style: normal">Physica B</i>, 404 (2009) 4083).
