Homogeneous nucleation is the initial stage of nanoparticle formation. The critical cluster size is one from the main parameters in the classical nucleation theory. The value of the critical cluster size is usually found from the Kelvin equation which does not depend on the condensation coefficient. In the general case the size dependence of the condensation coefficient can influence the critical cluster size (Levdansky, 2002). The size dependence of the cohesive energy in the nanoparticle can also affect the size of the critical cluster. Below we consider the joint influence of above-mentioned size effects on the critical cluster size, the rate of nucleation and the growth rate of arising nanoparticles.
