Abstract

The compression behavior of a natural scorodite has been investigated to about 8.21 GPa at 300 K for the fst time using in situ angle-dispersive X-ray diffraction and a diamond anvil cell at beamline X17C, National Synchrotron Light Source, Brookhaven National Laboratory. Over this pressure range, no phase change or disproportionation has been observed. The isothermal equation of state was determined for the frst time. The values of V₀, K _0, and K'₀ refned with a third-order Birch-Murnaghan equation of state are V₀ = 934.2 ± 0.3 Å³, K₀ = 61.8 ± 2.5 GPa, and K'₀ = 6.6 ± 0.9. Furthermore, we confrm that the linear compressibilities(β) along a, b and c directions of scorodite is elastically anisotropic.
