Zone melting

Zone melting (or zone refining or floating zone process or travelling melting zone) is a group of similar methods of purifying crystals, in which a narrow region of a crystal is melted, and this molten zone is moved along the crystal The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind ....
