Abstract:
We present in this paper an inhomogeneous cell model to describe the solid-fluid interface, In this interfacial model, an important parameter, the so-called surface scaling factor, and the key concept of effective growth units are introduced. This model enables us for the first time to calculate actual local bond energies at a particular crystal surface and to predict precisely the growth morphology of crystals. The formalism has been applied to n-paraffin crystal-solution systems. The results are compared with experimental ones, which turn out to be in excellent agreement with each other.
