A new fractional melting (FM) process that uses centrifugal force to separate the liquid from the cake (liquid+solid) was developed for refining metallurgical grade Si. The behavior of the solute and the refining mechanism during the FM process were studied using scanning electron microscopy
(SEM) and electron probe microanalysis (EPMA). During the FM, the solutes migrated very quickly and aggregated at seemingly disordered locations, where they subsequently melted before the silicon bulk matrix melted.
Journal for Nanoscience and Nanotechnology (JNN) is an international and multidisciplinary peer-reviewed journal with a wide-ranging coverage, consolidating research activities in all areas of nanoscience and nanotechnology into a single and unique reference source. JNN is the first cross-disciplinary journal to publish original full research articles, rapid communications of important new scientific and technological findings, timely state-of-the-art reviews with author's photo and short biography, and current research news encompassing the fundamental and applied research in all disciplines of science, engineering and medicine.
