Název v původním jazyce

Distribution of impurities in directionally solidified samples with planar crystallization front

Popis výsledku v původním jazyce

Method of directionally controlled solidification with planar crystallization front is used, as a rule, to purify the main component of impurities. It is considered that distribution of each impurity component along the length of directionally solidifiedsample with planar front is predetermined by the value of the equilibrium distribution coefficient (K) of each impurity with the main component. The K value is determined from equilibrium binary phase diagram as the relation K = CS / CL, where CS and CLare contents of the impurity under examination in coexisting solid and liquid phases. On condition that DS = 0 and DL = infinity and K < 1, at crystallization with planar front the impurity content along the length of the directionally solidified sampleincreases constantly and reaches maximum in the last part of the sample. In case of the value K > 1 the impurity content on the contrary decreases from the initial part of the sample to the final one.
