According to the classical nucleation theory the gap between nucleation temperatures of water on an insoluble particle and on a plane has been remaining. On setting the derivative of nucleation rate formula equal to zero, the freezing temperatures of supercooling water were calculated. The results show that the size of a tiny particle will have a larger effect on nucleation temperature, which coincides with the traditional conclusion. However, when a particle is of larger radius, its surface property will play an important role. Thus, along with that the geometry of a particle is closer to a plane gradually the freezing temperature will approach to the temperature of water nucleation on a plane until two temperatures join up. Therefore, the classical theory of liquid nucleation on an insoluble particle is not far beyond the range of macro. The analysis gives former experiments a theoretical support.
Keywords:water, nucleation rate, plane, insoluble particle
