In search of the mixed derivative ∂ 2 M/∂P∂T (M = G, K): joint analysis of ultrasonic data for polycrystalline pyrope from gas- and solid-medium apparatus

Gwanmesia, G D; Jackson, Ian; Liebermann, Robert

Description

Elastic wave velocities for dense (99.8% of theoretical density) isotropic polycrystalline specimens of synthetic pyrope Mg3 Al2Si3O12) were measured to 1,000 K at 300 MPa by the phase comparison method of ultrasonic interferometry in an internally heated gas-medium apparatus. The temperature derivatives of the elastic moduli [(∂Ks/∂T)P = -19.3(4); (∂G/∂T)P = -10.4(2) MPa K-1] measured in this study are consistent with previous acoustic measurements on both synthetic polycrystalline pyrope in a...[Show more]
