FAQ

What is the Surface free energy?

Surface free energy is the energy to create solid–liquid phase boundary during the solidification. Surface free energy is usually measured using the Joule per Square Meter for Heat Density. Note that the value of Surface free energy is always positive.

Can the Surface free energy be negative?

No, the Surface free energy, measured in Heat Density cannot be negative.

What unit is used to measure Surface free energy?

Surface free energy is usually measured using the Joule per Square Meter[J/m²] for Heat Density. Calorie (th) per Square Centimeter[J/m²], Langley[J/m²], Btu (IT) per Square Foot[J/m²] are the few other units in which Surface free energy can be measured.
