Description

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	Double-layer steel structure with air cooling 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 ºC 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 Faster travel: 35 mm/min
PVD 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 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 hanged 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 +/- 0.1ºC 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.
