SKJ-BG-1600 is a small 1700 Bridgman single crystal growth furnace, equipped with an outer diameter of Φ60mm alumina tube and a precise furnace movement mechanism (maximum traverse of 200mm). This equipment is designed for growing small-sized metal, oxide, and other single crystals in an atmosphere-controlled environment and can also be used for directional solidification of polycrystalline rods.

Travel Mechanism
|
-
Driven by a servo motor and a harmonic drive
- The servo motor and a high-precision linear module ensure that the furnace body moves smoothly.
- Two movement modes: slow lifting and fast movement
- Maximum travel distance: 200mm.
- Travel speed range: 0.03mm/hr ~ 30mm/hr (adjustable, with an accuracy of +/- 1um)
- The travel speed range can be customized at extra cost

Airtight Flanges
|
- A stainless steel water-cooled sealing flange system for sealing the alumina tube
- The top flange is equipped with a digital vacuum gauge and a Φ6.35mm gas outlet
- The bottom flange has a KF25 vacuum interface and a Φ6.35mm air inlet
- The bottom flange is driven by a stepper motor for lifting and loading the crucible
- The equipment comes with a graphite crucible with an outer diameter of Φ30mm, an inner diameter of Φ25mm, and a height of 50mm, with a shoulder angle inside
- The crucible holder is installed on the bottom flange
|
| Temperature Controller |
A Eurotherm EPC3000 temperature controller included
- PID automatic temperature control system
- Intelligent 24-segment programmable control
- DB9 PC communication port
- Temperature control accuracy: ±0.5
|
Control Panel
|
- Control the travel speed, travel distance, and furnace temperature
- Displays the crucible temperature
- Control the internal pressure of the furnace tube
- The temperature curve function displays the real-time temperature control curve and the temperature curve of the crucible, and the data can be saved, recorded, and exported
- It can be used with the heating furnace's heating curve to set the pre-pulling time, such as setting the pulling to start after 5 hours
- A digital vacuum gauge and an electromagnetic valve are installed on the sealed flange to control the constant pressure inside the furnace tube, with a control range of 0.01 MPa to 0.02 MPa

| 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)
