Abstract

The pressure and temperature parameters which delineate the equilibrium thermodynamic stability fields of the liquid, VI and VII phases, includinq the triple point, were measured for the H2;0 and D2;0 systems over the pressure range, 0.8 to 2.4 GPa, and the temperature interval, 20 to 135 °C. The phenomenon of metastability associated with the liquid-VII phase boundary was observed during this work; and, subsequently, a metastable extension of this coexistence curve was determined from the liquid-VI-VII triple point down to 20 °C for both H2;0 and D2;0. The measurements were made by optical polarizing microscopy in conjunction with a diamond anvil cell equipped with a miniature resistance coil heatinq element. Pressures were measured by the ruby fluorescence method.
