SummaryPreliminary work on a dielectric method of detecting the appearance or disappearance of ice crystals has been presented. The method seems to offer the possibility of making freezing-point depression measurements in colloidal materials under equilibrium conditions, hence making thermodynamic interpretation possible. The method offers possibility of use wherever ice separates as a pure phase during freezing. Some data have been obtained on water, sugar solutions, soil, and plant tissue, which indicate that the method can be used for determining freezing-point depressions in these materials. |
