Phase transition in waters with different content of deuterium

According to kinetics of temperature changes and laser light scattering on density heterogeneities we investigated waters with different content of deuterium in the area of their phase transition. It has been found out that protium/deuterium ratio substantially affects the process of phase transition water-ice-water in non-equilibrium conditions (the rate of temperature changes—2°C/min): temperature of light water ice melting (D/H = 4.2 ppm) constitutes 1.1 ± 0.3°C against 0.0 ± 0.3°C for high ohmic deionized water (D/H = 140 ppm) and 3.8 ± 0.3°C—for heavy one. Determined are special features of changes in phase state of water on the basis of concepts about water as a colloid system containing deuterium and stabilized gigantic heterophase clusters. © 2015, Allerton Press, Inc.
