Evidence from the paper
The K0 value thus obtained can be compared with those of Tamai and Yagi (1989), Mao et al. (1989), and Tarrida and Richet (1989), whose values are 288(13), 281(4), and 275(15) GPa, respectively. ... corrected pressure effects on volume using the Birch-Murnaghan equation of state with K0 = 281 GPa and K0' = 4 (Mao et al., 1989).
Additional notes
usage
K0 = 281 GPa and K0' = 4 from Mao et al. (1989) were used to correct pressure effects on volume for thermal expansion analysis in this study.
