About 26 kinds of simple and complex binary eutectics were frozen direction
ally under the condition of electromagnetic stirring. It was found that ano
malous eutectics including most metals/non-metals and some metal/intermetal
Iic eutectics, can be separated on macroscopic scale by flow caused by elec
tromagnetic stirring. Moreover, the eutectics in which one of their compone
nt phases possess an entropy of solution over 23 J mol(-1) K-1, showed nota
ble separation. In addition, process factors also affect the formation of a
separated eutectic. (C) 1998 Chapman & Hall.
