Evidence from the paper
Table 1. Results for B'∞ predicted from Eq. (11) based on the Roy-Roy EOS: 'MgO | 4.370 | 1.94' where the first column is B0' (from ref. 14) and the second is the upper limit on B'∞. Also: 'Values of the parameters a, b and c are determined using Eqs. (6)–(8) and (10), and the data on B0, B0' and B0B0''.'
Additional notes
B infinity prime upper limit
2.15
B infinity prime upper limit note
Table 1 second column states B'∞ must be less than 1.94 for MgO
note
No V0 or K0 (B0) value is numerically reported for MgO in this paper; only B0' is tabulated. The paper's Earth-interior application concerns the core (hcp iron, B0 = 170 GPa, B0' = 4.98), not the lower mantle; MgO appears only in a generic solids compilation.
