Why this differs from similar rows?
Cites Mao et al. [1991] XRD to 30 GPa, K'0=4; sibling rows cite different original studies (Ross and Hazen 1990; Fiquet et al. 1998).

Evidence from the paper
This bulk modulus is also compatible with previous measurements to 30 GPa by Mao et al. [1991] who reported 261 GPa (K'0=4).
