The report describes a novel technique for floating zone crystal growth in which a resistively heated filament is immersed directly in the molten zone. Two furnaces employing this technique are described in some detail. Various considerations for the design of the filaments and for the preparation of feed rods are also discussed. Finally, experiments in the growth of apatite, spodumene, LiNbO3, sapphire, KTN and KC1 are discussed.
