網頁Fractional crystallization, or crystal fractionation, is one of the most important geochemical and physical processes operating within crust and mantle of a rocky planetary body, such as the Earth. It is important in the … The interface between a crystal and its vapor can be molecularly sharp at temperatures well below the melting point. An ideal crystalline surface grows by the spreading of single layers, or equivalently, by the lateral advance of the growth steps bounding the layers. For perceptible growth rates, this mechanism requires a finite driving force (or degree of supercooling) in order to lower the n… 網頁Crystallization Steps While the method chosen to crystallize product can vary based on several factors, there are six common steps for crystallization to occur.

網頁Crystallization occurs in two major steps. The first one is nucleation, which gives the looks of a crystalline phase from either a supercooled liquid or a supersaturated solvent. The second step is understood as crystal growth, which is the increase within the size of particles and results in a crystal state.
