Tungsten & Molybdenum Components
Sapphire Growth Furnace Components
Over the past five years, as LED lighting substrate and consumer electronic touch screen marked expanded, sapphire crystal industry got the best opportunities than ever before.
Tungsten and molybdenum products for sapphire growth furnaces materials is purity higher than 99.95% . Including tungsten crucible, tungsten plate, tungsten heat shield , tungsten wire, tungsten electrode screen, Tungsten drum, tungsten heat shield, molybdenum crucible, molybdenum insulation screen, molybdenum heating element, molybdenum hot zone, molybdenum support frame and molybdenum electrode screen. In addition, tungsten rhenium wire is also a necessary products in sapphire furnace.
5. Molybdenum Seed Chuck & Tungsten Heater
The sapphire melting point is 2045℃，it is such a high temperature that plenty of high melting point metal such as tungsten and molybdenum are used in the process of sapphire growing.
The methods of crystal growth:
- KY Method: Kyropoulos Method
- TGT Method
- EFG Method：Edge Defined Film-fed Growth
- HEM Method： Heat Exchange Method
- VHGF Method：Vertical Horiaontal Gradient Freezing Method
- Horizontal Bridgman method
- KY Method 、HEM and EFG method are mainly used methods.
