Notes:
In this paper, the thermodynamic and kinetic requirements of heterogeneous andhomogeneous nucleation of metallic melting were suggested. Based on the kinetic requirements ofnucleation, the mathematic model of wetting angle of heterogeneous nucleation was developed,Based on the wetting angel model, it was predicted that the maximum undercooling of homogeneousnucleation for melts is two thirds of melting temperature. With the wetting angel model, the wettingangles of different catalysts in liquid iron were calculated, and calculation results are in agreementwith that of other researchers
