Part of the Springer Series in Solid-State Sciences book series (SSSOL, volume 5)


The discussion of phase transitions in Chapters 3 and 4 has shown that only monocomponent and congruently melting or vaporizing multicomponent systems, respectively, remain unchanged in composition during solidification or crystallization. In all other systems the composition of the solid differs from that of the coexisting fluid (liquid or vapor) even in equilibrium. This phenomenon is called segregation or redistribution. In this chapter we will be mainly concerned with “impurities”, i.e., concentrations of solutes of, say, a few percent and below. We will, however, emphasize the consequences of adding large concentrations of components (solvents, inert gases) for the formal description of segregation dynamics.
