Evidence from the paper

Table II: Values of input parameters used in the present work. MgO: r0 = 2.105 Å [15], alpha0 = 0.312 [10^-4 k^-1] [15], B_T0 = 173 [kbar] [15], delta_T0 = 4.29 [16]. 'Anderson and Zou [11] have reported the pressure-volume data for MgO.'

Additional notes

r0
2.105 Å (interatomic separation at P = 0, cited from [15]); no unit-cell or molar V0 is reported, so V0 fields are left empty
alpha0
0.312 x 10^-4 k^-1 (volume thermal expansion coefficient at V = V0, cited from [15])
delta T0
4.29 (Anderson-Grueneisen parameter at V = V0, cited from [16])
k
1.5 (dimensionless thermoelastic parameter, assumed following Anderson et al. [6, 7])
note on Kp
This EOS formulation does not use K' (K prime); pressure dependence of B_T is expressed through delta_T0 and k via Eq. (12)
pressure range
calculations performed up to ~45 kbar (Table VI extends to 109.00 kbar for MgO)
parameter sources
input parameters cited from references [15] and [16], not fitted in this study
