WebApr 1, 2024 · For sodium sulfate soils with salt content from 0% to 1%, the onset temperature of heat flow decreases from −7.26 °C to −8.16 °C (Fig. 11 a–e). Moreover, there is only a peak on the curve of heat flow for these sodium sulfate soils, which indicates existence of a singular phase change between water and ice, without salt crystallization.
