| Abstract: | Pressure P, bulk modulus K and its first and second pressure derivatives K' and K'', and the
Grüneisen parameter  and its volume derivative q for
NaCl crystal down to a compression, V/V0
= 0.65 have been studied. These properties have been calculated along different
isotherms at selected temperatures in the range 300-1050 K using Holzapfel AP2
equation of state. The results obtained have been found to be in good agreement
with the data reported in the literature. A reciprocal K-primed equation, quadratic in P/K, has been found to satisfy the
relationship between P, K and K' along with different isotherms, and is also consistent with the
values of K'' at different compressions and temperatures. Volume dependence of
the Grüneisen parameter has been discussed in terms of the existing recent
formulations. |
