Through visualization of the freezing interface during directional solidification of succinonitrile containing ethanol on a rotating table, it was shown that rotation about the ampoule axis might reverse solute distribution and remove pit formation. Simulation was also conducted to explain the observations.application/pdf266450 bytesapplication/pdfen-USA1. Centrifugal forceA1. ConvectionA1. InterfaceA1. RotationA1. SegregationA2.
