HT-1700-PVT is designed for growing SnO2 single crystal by PVT methods ( Physical Vapor Transport) under a controlled atmosphere up to 1700℃ 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 | l Heating zone length: 200mm l Constant temperature zone: 70mm within +/-1°C l 50 mm dia alumina tube with vacuum-sealed rotation and pulling mechanism. l MoSi2 heating elements with Max. 1700°C working temperature l Eurotherm temperature controller with +/- 0.1°Caccuracy. l Voltage: 208-240 VAC, single phase, 50/60Hz l Power: up to 4 kW |
Alumina Tube and Flanges | l High purity alumina Tube size: 50mm OD x 40 mm ID x 1000 mm L l Top flange: water-cooled flange with a needle valve and a KF25 port for rotation and pulling mechanism. l Bottom flange: flange with a needle valve and KF25 port for connection to a vacuum pump. l Two 1/4" tube fitting for gas circulation or flow. l Working gases: Inert gas, CO2, and oxygen gas up to 0.2 MPa. |
Pulling Mechanism | l Travel is driven by precision servo motor l Pulling Speed: 0.1 - 10 mm/hr. l Pulling Rod Rotation Speed: 0.1 - 23 RPM l Travel distance: 0 - 300 mm l Faster travel: 35 mm/min |
CZ Method | l Source raw materials will be put in the bottom flange with an included alumina rod. l The seed crystal ( substrate ) will be fixed in the pulling rod on the top flange. l The seed crystal will keep a constant distance from the crucible, and slowly move up with crystal growth during heating l Inert gas or CO2 gas will be filled in the processing tune during crystal growth up to 2 bar pressure. |
Bridgeman Method | l The source material will be put in a crucible with V type bottom with a crystal seed. l The crucible will be hung upon the pulling rod on the top flange l The crucible will rotate and move up during heating to grow a single crystal |
Temperature Control and Profile | l Two Eurotherm temperature controllers with two K-type thermocouples are builtin with +/- 0.1º°Caccuracy. l 28 segments programmable with PID adjustable for two heating zone independently. l RS485 port and software (iTools) is ready for PC remote control l Note: It is the customer's responsibility to create a suitable thermal gradient for crystal growth. |
Vacuum Pump and Gas Purification System (Optional) | l 10E-2 torr via dual-stage mechanical vacuum pump l 10E-5 torr via Turbopump l The vacuum pump is optional. l For oxygen-sensitive material, suggest using a recirculating gas purification system ( H2O, O2 < 1 ppm) to replace the turbopump |
Water Chiller (Optional) | l A water chiller is required to prevent top flange overheating but it is not included in the standard package. |
Dimension & Weight | l Weight: 105 kg l Size: L×W×H: 860 mm×740 mm×2160 mm |
Warranty | l One-year limited warranty and lifetime technical support |
Crystal Growth furnaces are used to grow high-quality single crystals with uniform properties and low defect density.Crystalline materials play a vital role in science and industry, leading the development of modern materials in applications such as semiconductors, optics, and electronics.
