Evidence from the paper
a variation of isothermal bulk modulus between 160 (±2) GPa for MgO and 154 (±3) GPa for (Mg0.64Fe0.36)O is given by x-ray diffraction measurements [Fei, 1999; Dewaele et al., 2000; van Westrenen et al., 2005]
Additional notes
adiabatic ultrasonic values
isentropic bulk modulus 160–162.5 (±3.0–0.5) GPa for pure MgO [Jackson et al., 1978; Jackson and Niesler, 1982; Bonczar and Graham, 1982; Jacobsen et al., 2002]
