A phase transition in H2O due to electrostriction pressure

Abstract

It is predicted that water at ambient conditions should undergo a phase transition to a dense phase of H2O at a transition value Πt of the local electrostriction pressure. The transition is accompanied by a latent heat as well as discontinuity in entropy and electric field. The values of the field in which recent X-ray scattering at a charged RuO2/water interface revealed phase transitions to very dense ordered H2O layers are met without adjustable parameters. The latent heat has been observed earlier at a Hg/aqueous electrolyte interface. An attempt at an explanation of the hydration of Sr2+ ions is undertaken.
