Analysis of volume dependence of thermal expansivity for NaCl

Kumar, Sanjay ; SHARMA, S K ; Pandey, O P


In the present paper, a suitable model to evaluate the volume dependence of thermal expansivity α by using the reciprocal form of volume dependence of Anderson-Grüneisen parameter (δT) has been proposed. The newly developed relationship has satisfied the constraints of infinite pressure behavior, i.e., P → ∞ or V → 0. The results obtained through the present model show the consistency with the experimental data for NaCl.
