WebFloating Zone (Crucible-Free Zone Melting) The floating zone (FZ) technique is a crucible-free crystal growth method. In FZ growth, the molten zone is kept between two vertical solid rods by its own surface tension (Figure 17 ). A single crystal is grown by dipping a seed crystal into one end of the zone and translating the molten zone toward ...
