- Adiabatic pressure derivatives;
- Gruneisen parameter;
Temperature changes caused by small rapid pressure changes have been measured for quartzite, single-crystal quartz, and fluorite to 36 kbar. The Grüneisen parameter was then calculated from the adiabatic pressure derivative of temperature (∂T/∂P)S by use of the thermodynamic relationship γ = KS/T (∂T/∂P)S where KS is the adiabatic bulk modulus. The measurements were carried out in a piston cylinder apparatus using alcohol as a pressure transmitter. Parameter γ for quartz and quartzite slightly decreases with pressure, whereas we note a large decrease in γ for fluorite with pressure. We find values for q = − (∂ ln γ/∂ ln V)T of 2.0, 1.7, and 4.6 for quartz, quartzite, and fluorite, respectively.
