IMPURITY TRAPPING DURING SOLIDIFICATION OF A SIMPLE EUTECTIC BINARY MELT - THEORY AND EXPERIMENTS

摘要

Measurements of impurity concentration in the crystal layer grown on a cooledrnsurface are performed with a binary organic melt of myristic acid and palmitic acid.rnIn order to validate a new theory of interfacial solute distribution proposed by thernpresent authors [1], direct numerical simulations of melt crystallization are carriedrnout. The predictions of impurity concentration profiles in crystal are compared wellrnwith the measurements.
