Abstract

We have measured the density of liquid Fe_98.3O_1.7 in the P-T range of 1.4 - 6.1 GPa and 1950 - 2250 K using X-ray absorption method at BL22XU. Microprobe analysis of the recovered samples showed the reaction between the sample and BN spacer. After removing the BN contribution to the sample density, the estimated densities of liquid Fe-O increase from 6.71 to 7.08 g⁄cm3 with pressure at 2200 K.
