Phase diagram of ice: dark blue-, green-, and red-shaded regions denote ice VII, VIIt and X, respectively, and projected phase boundaries separating high-pressure ice phases from our work are shown as solid black lines; ice X phase boundaries connect the measured transition at 30.9 GPa and 300 K to the inflection point in the melt curve, which have been associated with the transition from molecular to ionic fluid; dashed lines show measured melting curves; superionic boundary is highlighted.

New Form of Ice Discovered: Ice VIIt

Mar 21, 2022 by News Staff

Physicists have observed the transition from a previously known cubic phase, ice VII, to the newly-discovered intermediate, and tetragonal, phase, ice...
