Critical Free Energy for Nucleation Calculator

Calculate Critical Free Energy









Formula

The formula to calculate the critical free energy for nucleation is:

\[ \Delta G = \frac{16 \pi \gamma^3 T_m^2}{3 \Delta H_f^2 \Delta T^2} \]

Where:

Definition

Critical free energy is the energy required for the formation of stable nuclei during the phase transition.

Surface free energy is the energy required to create a solid–liquid phase boundary during solidification.

Melting temperature is the temperature at which a metal or alloy transitions from solid to liquid.

Latent heat of fusion is the heat released during solidification, measured in Joules per cubic meter.

Undercooling value is the difference between the melting temperature and the temperature under consideration, also known as supercooling.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \Delta G = \frac{16 \pi (0.2)^3 (1000)^2}{3 (1,200,000,000)^2 (100)^2} \approx 9.30842267730309 \times 10^{-18} \, \text{J} \]

The critical free energy is approximately \(9.30842267730309 \times 10^{-18}\) Joules.
