N2 - A new synchrotron X-ray diffraction study of ε-FeOOH has been carried out to determine the pressure-volume- temperature (P-V-T ) equation of state (EOS). The P-V-T data fitted a third-order Birch-Murnaghan EOS yielded: isothermal bulk modulus KT0 of 135(3) GPa; its pressure derivative K' of 6.1(9); (∂KT/∂T )P of -0.05(2) GPa K-1; a0 of 2.6(7) × 10-5 K-1 and a1 of 1.0(3) × 10-7 K-2, where the volumetric thermal expansion coefficient is described as α0,T = a0 + a1 × (T - 300).
