SKJ-BG-1200 is a small 1200ºC Bridgman crystal growth furnace with a 72 mm ID quartz tube and precision travel mechanism, which is designed for growing small size crystals under control atmosphere up to 1200oC
SPECIFICATIONS:
Vertical Two Zone Tube Furnace
|
- Compact two zones split vertical tube furnace
- Working Voltage: 208 - 240V selectable
- Max. Power Consumption: 4.0 KW
- Two Heating Zone: 100 mm L for each Zone, 200 mm L in total
- Max. heating temperature: 1200°C
- Continuous working temperature: 1100°C
- Two programmable digital temperature controllers which control two heating zone independently
- Max. Temperature gradient: 1ºC/Cm
- Finding a suitable thermal gradient is the user's responsibility
- Adjusting two heating zone's temperatures can create different thermal gradient profile
- Adjusting the furnace opening diameter also can change the thermal gradient
- A quartz tube (80mm O.D x 72mm I.D x 800mm L) is included with an airtight flange)
|
Travel Mechanism
|
- DC motor with precision screw drives the furnace up or down for crystal growth
- Travel distance: 200 mm Max.
- Travel speed range: 0.03 mm /hr. - 30 mm /hr. adjustable with +/- 1 micron accuracy ( standard)
- Customized speed range is available upon request
|
| Airtight Flanges |
- One pair of air-tight flanges is included for atmosphere control under a vacuum
- The top flange has a mechanical vacuum gauge and 1/4" gas inlet
- The bottom flange has a KF25 vacuum port and 1/4" gas outlet
- Vacuum level: 10-2 torr by mechanical pump and 10-5 torr by a turbopump

|
| Crucible & Holder |
-
Quartz crucible: Ø42 × Ø36 × 38 mm
- Quartz sample stage for crucible up to Ø43.5×18 mm
|
Control Panel
|
- A touch screen control PC is included for control travel speed, travel distance, temperatures of the furnace and crucible temperature separately, as well as gas pressure inside the tube.
- Two Eurotherm controllers and two K-type thermal couples are included with +/- 0.1 oC accuracy
- PID temperature control, with 24 temperature segments
- One thermal couple controls the temperature of the furnace
- One thermal couple displays the temperature of the crucible at its bottom
- One digital pressure sensor with solenoid valves is installed for controlling tube pressure at the constant from 0.01MPa - 0.02MPa

| Optional |
- 10E-2 torr via dual-stage mechanical vacuum pump (Pic. 2)
- 10E-5 torr via Turbopump (Pic. 1)
- The vacuum pump is optional. Please click here to choose a vacuum pump.
- For oxygen-sensitive material, suggest using a recirculating gas purification system ( H2O, O2 < 1 ppm) to replace the turbopump (Pic. 3)
