Hybrid Crystal Grower For Both CZ & Bridgman up to 1700°C w/ Atmosphere Control - OTF-1700X-PVT

Hybrid Crystal Grower For Both CZ & Bridgman up to 1700°C w/ Atmosphere Control - OTF-1700X-PVT

OTF-1700X-PVT is designed for growing SnO2 single crystal by PVT methods ( Physical Vapor Transport) under a controlled atmosphere up to 1700oC at an affordable cost. It also can be used to grow the crystal by the Bridgman method via pulling a crucible.

 Specifications

Vertical Tube Furnace
  • Heating zone length: 200mm
  • Constant temperature zone: 70mm within +/-1ÂșC
  • 50 mm dia alumina tube with vacuum-sealed rotation and pulling mechanism.
  • MoSi2 heating elements with Max. 1700°C working temperature
  • Eurotherm temperature controller with +/- 0.1 ÂșC accuracy.
  • Voltage: 110V or 208-240 VAC, single phase, 50/60Hz
  • Power: up to 4 kW 
Alumina Tube and Flanges
 
  • High purity alumina Tube size: 50mm OD x 40 mm ID x 1000 mm L
  • Top flange: water-cooled flange with a needle valve and a KF25 port for rotation and pulling mechanism.
  • Bottom flange: flange with a needle valve and KF25 port for connection to a vacuum pump.
  • Two 1/4" tube fitting for gas circulation or flow. 
  • Working gases: Inert gas, CO2, and oxygen gas up to 0.2 MPa.
Pulling Mechanism 
  • Travel is driven by precision servo motor
  • Pulling Speed: 0.1 - 10 mm/hr.
  • Pulling Rod Rotation Speed: 0.1 - 23 RPM
  • Travel distance: 0 - 300 mm

CZ Method
  • Source raw materials will be put in the bottom flange with an included alumina rod.
    • Crucible is not included, please click here to choose one
  • The seed crystal ( substrate ) will be fixed in the pulling rod on the top flange.
  • The seed crystal will keep a constant distance from the crucible, and slowly move up with crystal growth during heating
  • Inert gas or CO2 gas will be filled in the processing tune during crystal growth up to 2 bar pressure.
Bridgeman Method
  • The source material will be put in a crucible with V type bottom with a crystal seed.
  • The crucible will be hung upon the pulling rod on the top flange 
  • The crucible will rotate and move up during heating to grow a single crystal
Temperature Control and Profile
 
  • Two Eurotherm temperature controllers with two K-type thermocouples are builtin with +/- 0.1ÂșC accuracy.
  • 28 segments programmable with PID adjustable for two heating zone independently.
  • RS485 port and software (iTools) is ready for PC remote control
  •  Note: It is the customer's responsibility to create a suitable thermal gradient for crystal growth.
Vacuum Pump
and
Gas Purification System
(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) 
  •  Pic. 1 Pic. 2  Pic. 3

Water Chiller
(Optional)

  • A water chiller is required to prevent top flange overheating but it is not included in the standard package.
