Evidence from the paper
'... at 300 K, MgO is more compressive than stoichiometric FeO, with K0S = 162.5(2) GPa for MgO (Jackson and Niesler 1982)'.
Additional notes
context
Ambient adiabatic bulk modulus of end-member periclase; abstract also notes K0S = 162-163 GPa and K0T ≈ 160 GPa at ambient conditions.
