The interfacial tension, γ, between crystals and the solution plays a key role for the rate of nucleation of crystals. Attempts have been made to measure the value by measuring the incubation time for nucleation and the 1 /σ^2 where a is the supersaturation of the solution. The discrepancy of γvalues under gravity and under microgravity was interpreted as the dominant heterogeneous nucleation under gravity, whereas under microgravity homogeneous nucleation is dominant. Theγvalue can be varied by adding some impurities to the solution, which not only changes crystallization rate but also modifies the polymorphs. Since the change ofγis the result of modification of the growing/ dissolving interface, extensive AFM works have been done on calcite surface. Some AFM works and DLS works have been reviewed, so that the importance of theγvalue could be realized.
