It is found that, at sufficiently small growth rates, particles of nearly all materials are rejected by a moving crystal-liquid interface, ie, they are pushed ahead into the liquid, traveling along with the interface as it advances [2]. Particles moving along with the interface can be observed to impinge upon other particles in the liquid. These in turn are pushed by the particles at the interface, and move along as the interface advances....
