Floating zone furnace

Ruby made by this furnace

machine specifications:

• Compact floating zone (FZ) furnace for single crystal growth
• Manufactured by NEC Machinery Corporation, Japan
• Heated by two halogen lamps (650Wx2), and could reach up to 2100 C
• Melt is supported by surface tention, and no crucible is necessary
• Single crystals up to 4mm in diameter and 50mm in length
• Sample atmosphere can be controlled (atmosphere controller must be supplied)
• Sample can be monitored by a CCD camera during growth process
• Upper and lower main axes can be rotated and moved independently

applications:

• Single crystal growth of oxides and silicates
• Incongruent melting crystals can be grown by traveling solvent technique
• Synthesis and melting of high refractory materials not possible by ordinary furnaces
• Study of melt properties (need neat idea and some modifications)
