Evidence from the paper
TABLE I. Single-crystal and aggregate elastic moduli of MgO (in GPa) and their pressure derivatives. Pressure derivatives of bulk and shear moduli are calculated from finite-strain equations of state. This study: K0 163.2(10); K0' 4.0(1); K0'' -0.04(2). 'an iterative procedure was used to obtain the density, Cij's, and isotropic aggregate elastic moduli using a fourth-order finite strain equation of state (EOS).'
