Thermodynamic modeling of processes that occur during zone melting with electrical and thermal transfer in the liquid zone

Abstract

Theoretical modeling of crystallization during zone melting (ZM) in metallic systems is performed using the concepts of nonequilibrium thermodynamics. An equation that is more correct and convenient for practical discussion of experimental data is derived for calculating the impurity distribution coefficient in ZM. Allowing for electrical transfer, convective diffusion during operation, and the released Peltier heat, the results agree with the literature data for the Bi–Sn system.
