DSC measurements of the thermal properties of gallium particles in the micron and sub-micron sizes, obtained by sonication of molten gallium

The thermal behavior of gallium microparticles, in comparison with bulk gallium, was examined by differential scanning calorimetry. All the samples showed a single endothermic signal for melting near the known melting point of gallium. Cooling the molten samples showed super-cooling effect, which was more pronounced for the gallium microparticles than for the bulk metal.
