Three Heating Zone Bridgman Furnace
For any inquiry, please send to this email: sales@gensitherm.com
This is a 1650°C max. Bridgman furnace for directional solidification and single crystal growth with a boule size up to Ø37mm.
This is a 1650°C max. Bridgman furnace for directional solidification and single crystal growth with a boule size up to Ø37mm.
The vertical furnace has three independently controlled heating zones with a total heating length of 300 mm to set up different temperature gradients for crystal growth.
In contrast to other Bridgeman systems, it keeps the melt stationary while moving the furnace up to control the temperature gradient, ensuring the stability of the growth interface.
The sample rotational stage can be added at an additional cost for single crystal growth.
Specifications:
| Advanced Features | Three (3) independently controlled heating zones for temperature gradient tuning.
φ42mm Alumina sample pulling stage with TC attachment for accurate temperature monitoring of the crucible at the bottom. Electric elevated crucible stage enables an automatic and convenient sample loading/retrieving. |
| Power Requirements | 220VAC single phase 50/60Hz
9.5KW |
| Working Temperature | Heating Element: Silicon molybdenum rod
Max. Working Temperature: 1700°C ( <1hr) Continuous Operating Temperature: 1600°C
|
| Processing Tube & Flange | High purity alumina furnace tube, Size: φ80mm O.D. x 74 mm ID x 1000mm L
A pair of stainless steel flange is connected to both end of the processing tube which allows for inert gas purging or vacuum during the crystal growing process |
| Sample Stage | φ42X40mm H Alumina Sample Stage
B type thermocouple insert from the bottom of the sample stage for accurate temperature measurement of the crucible |
| Crucible Retrieving Mechanism | Automatic sample retrieving system for easy crucible loading/unloading,
700mm max. travel distance |
| Heating Zones | Three heating zones with independent temperature measurement and control
Three zones: 300mm (12″) long in total 100mm long for each zone |
| Temperature Control | Three EPC 3004 Eurotherm temperature controller with 28 programmable segments for precise control of heating, cooling, and dwelling rate.
Built-in overheating & broken thermocouple protection. Temperature controller, with +/- 0.1 ºC temperature accuracy. Three B type thermocouples (one for each zone). |
| Cooling Fans | One speed adjustable cooling fans are installed at the bottom exit of the furnace |
| Furnace Travel Distance & Speed | As the furnace heater moves upward, the crucible is moving toward the bottom exit of the furnace where the lower temperature is seen.
The maximum travel distance of the furnace heater is 200 mm. Travel speed: 0.03-3 mm/hr |
| Vacuum Pump (Not included) | 10E-2 torr via dual-stage mechanical vacuum pump
10E-5 torr via Turbopump The vacuum pump is optional. For oxygen-sensitive material, suggest using recirculating gas purification system ( < 1 ppm) to replace turbopump |
| Optional & Related Products | For single crystal growth, the rotation of the crucible stage is needed, an additional cost will apply.
A board selection of crucible materials: Boron Nitride; Alumina; Zirconia; Graphite…. Grown crystal boules: Al, Ag, Au, Cu, Mg, Ni |
