Scientific paper

We have measured the compressibility of CsCl-structured FeSi to 40 GPa by X-ray powder diffraction using synchrotron radiation. A third order Birch-Murnaghan equation of state fit to the experimental data yields V0 = 21.74 +/- 0.02 Å, with a K0 of 184 +/- 5 GPa and K'0 = 4.2 +/- 0.3. The measured density and elastic properties of CsCl-FeSi are consistent with silicon being a major element in the Earth's core.
