In porous materials filled with water or water solutions of inorganic salts, water freezes at lower temperatures than under normal conditions; the reason is the decrease of water vapor tension above the convex meniscus of liquid in pores. The freezing point depression is not very significant in pores with radii from 0.05 μm to 10 μm (about 0.01-2.5 K). Only in smaller pores, especially when filled with inorganic salt solutions, this depression is important.

The cooling curves of a number of solutions of deuterium peroxide in heavy water in the concentration range 11% to 95% were measured in order to determine the solid-liquid phase diagram for that binary system. The apparatus of Herington and Handley, which uses a pulsing pressure for stirring the solutions, and a thermistor, was found to be particularly suitable for that purpose. As could be expected the freezing-point curve of the deuterated compounds is closely similar to that of the hydrogen compounds, being shifted up only by about 4° for water-rich solutions and by 2° for peroxide-rich solutions. The melting point of the addition compound, D2O.2D2O very nearly coincides with one of the eutectic points at 46.2% D2O2 and −51.5 °C.; the other eutectic point is at 60.5% D2O2 and −55.1 °C. By extrapolation the melting point of pure deuterium peroxide is found to be 1.5 °C. as compared with −0.43 °C. for hydrogen peroxide. Concentrated solutions of deuterium peroxide exhibit an extreme tendency to supercool, resulting sometimes in formation of glasses even at liquid-air temperature. The previous results of Foley and Giguère for the system H2O–H2O2 were confirmed, specially as regards the melting point of the addition compound H2O2•2H2O.
