Temperature and pressure-induced phase transitions in ice

International audience ; In the liquid state, water molecules tend to be surrounded tetrahedrally by four other molecules. This tendency gives rise to a three-dimensional open network which is a feature of most of the solid phases: in addition to the many polymorphic crystalline forms presently known, there exist glassy and amorphous ices with unique hydrogen-bonded structures. In this paper, we briefly review the structural properties of the crystalline and non-crystalline phases including the more recent data quoted in the literature.
