Evidence from the paper
Vanpeteghem et al. (2003) performed an X-ray powder diffraction study on phase egg to a maximum pressure of 40 GPa at room temperature and described its compressibility using a third-order Birch-Murnaghan equation of state with a room-pressure bulk modulus K0 = 157(4) GPa and its pressure-derivative K0ʹ = 6.5(4). Table 2 'published' column: K0 (GPa) 157(4); K′ 6.5(4).
