Supercooling, undercooling and nucleation.

Volmer and Weber kinetic model[edit]

Volmer and Weber kinetic model [1] results in the following nucleation rate:

Szilard nucleation model[edit]

Homogeneous nucleation temperature[edit]

The homogeneous nucleation temperature () is the temperature below which it is almost impossible to avoid spontaneous and rapid freezing.

Zeldovich factor[edit]

The Zeldovich factor [2] () modifies the Volmer and Weber expression, making it applicable to spherical clusters:

Zeldovich-Frenkel equation[edit]

Zeldovich-Frenkel master equation is given by
