The compression behavior of a natural hauyne has been investigated to about 8.1 GPa at 300 K using in situ angle-dispersive X-ray diffraction and a diamond anvil cell at High Pressure Experiment Station, Beijing Synchrotron Radiation Facility (BSRF). Over this pressure range, no phase change or disproportionation has been observed. The isothermal equation of state was determined for the first time. The values of V(0), K(0), and K'(0) refined with a third-order Birch-Murnaghan equation of state are V(0)=751.6 +/- 0.4 angstrom(3), K(0)=49 +/- 1 GPa, and K'(0)=3.3 +/- 0.3, respectively.
