    Abstract
  • We have studied the equation of state (EOS) of aluminium by using energy dispersive synchrotron radiation X-ray diffraction technique at room temperature under in situ pressures up to 21.5 GPa. The data were fitted to Murnaghan equation of state and gave the bulk modulus and its first order derivative of aluminum: B0=(772) GPa, B0= 4.80.3. We attributed the small deviation of our result from those in the literature to the nonhydrostatic effects caused by the pressure transmitting medium NaCl. Yet we have not found any convincing evidence for a phase transformation in the experimental pressure range.
