Abstract

<p>A new synchrotron X–ray diffraction study of ε–FeOOH has been carried out to determine the pressure–volume–temperature (<i>P</i>–<i>V</i>–<i>T</i>) equation of state (EOS). The <i>P</i>–<i>V</i>–<i>T</i> data fitted a third–order Birch–Murnaghan EOS yielded: isothermal bulk modulus <i>K</i><sub>T0</sub> of 135(3) GPa; its pressure derivative <i>K</i>′ of 6.1(9); (∂<i>K</i><sub>T</sub>/∂<i>T</i>)<i><sub>P</sub></i> of −0.05(2) GPa K<sup>−1</sup>; a<sub>0</sub> of 2.6(7) × 10<sup>−5</sup> K<sup>−1</sup> and a<sub>1</sub> of 1.0(3) × 10<sup>−7</sup> K<sup>−2</sup>, where the volumetric thermal expansion coefficient is described as <i>α</i><sub>0,T</sub> = a<sub>0</sub> + a<sub>1</sub> × (<i>T</i> − 300).</p>
