Heat of Fusion of the Elements

Unit

The enthalpy of fusion, or latent heat of fusion, is the energy required to change a substance from solid to liquid at constant pressure without a change in temperature. The heat of solidification (liquid to solid) is equal and opposite.

Data available for 93 of 118 elements. Highest: Carbon (105 kJ/mol). Lowest: Helium (0.02 kJ/mol).
