Abstract

The x-ray structure factor of water has been measured along the melting line to 57 GPa and 1500 K using focused monochromatic synchrotron radiation and laser heated diamond anvil cell. The oxygen radial distribution function, g(r) is determined from these data. We have also calculated g(r) using ab initio methods and find a good agreement with the experiment. Based of the similarity of the measured and calculated structure factors determined density of water under extreme conditions unattainable previously.

The 4 GPa pattern actually looks close to the structure of ice VI (1st dOO=2.83 A, coordination number CN=4; 2nd shell dOO=3.49 A, CN=8; 3rd shell dOO=3.97 A, CN=4; all 3 shells might contribute to the first ring in g(r). The calculated CN for the 4 GPa pattern is 14.1, compared to 9.2–10.2 for the higher pressure patterns. The coordination numbers have been calculated as follows: CN= ρNA/18e-3*∫0 rmin 4 πr2g(r)dr, where rmin corresponds to the minimum of g(r) after the 1st peak.Google Scholar
