Question:
Draw the free energy curves for heterogeneous nucleation at a flat mold wall as a function of radius of the solid particle assuming a spherical cap geometry. Describe the curve briefly by indicating all contributions to this curve as well as all critical terms of relevance for nucleation. In particular, what is required for the formation of a critical nucleus that can grow? Using the above analysis explain why heterogeneous rather than homogeneous nucleation occurs in practice
