1650°C Bridgman Furnace for Directional Solidification and Crystal Growth

HT-1650C is a 1650°C max. Bridgman furnace for directional solidification and single crystal growth with a boule size up to Ø37mm.The vertical furnace has three independently controlled heating zones with a total heating length of 300 mm to set up different temperature gradients for crystal growth.STA-1650C keeps the melt stationary while moving the furnace up to control the temperature gradient, ensuring the stability of the growth interface.

Specifications:

Advanced Features

Three (3) independently controlled heating zones for temperature gradient tuning. 

φ42mm Alumina sample pulling stage with TC attachment for accurate temperature monitoring of the crucible at the bottom.

Electric elevated crucible stage enables an automatic and convenient sample loading/retrieving;

Power Requirements

220VAC single phase 50/60Hz

9.5KW

Working Temperature 

Heating Element: Silicon molybdenum rod

Max. Working Temperature: 1700°C ( <1hr)

Continuous Operating Temperature: 1600°C

 Processing Tube & Flange

High purity alumina furnace tube, Size: φ80mm O.D. x 74 mm ID x 1000mm L

A pair of stainless steel flange is connected to both end of the processing tube which allows for inert gas purging or vacuum during the crystal growing process

Sample Stage

φ42X40mm H Alumina Sample Stage

B type thermocouple insert from the bottom of the sample stage for accurate temperature measurement of the crucible

Crucible Retrieving Mechanism

Automatic sample retrieving system for easy crucible loading/unloading, 

700mm max. travel distance

Heating Zones

Three heating zones with independent temperature measurement and control

Three zones: 300mm (12") long in total, 100mm long for each zone.

Temperature Control

Three EPC 3004 Eurotherm temperature controller with 28 programmable segments for precise control of heating, cooling, and dwelling rate. 

Built-in overheating & broken thermocouple protection.

European Temperature controller, with +/- 0.1 ºC temperature accuracy.

Three B type thermocouples (one for each zone).

Cooling Fans

One speed adjustable cooling fans are installed at the bottom exit of the furnace

 Furnace Travel Distance & Speed

As the furnace heater moves upward, the crucible is moving toward the bottom exit of the furnace where the lower temperature is seen. 

The maximum travel distance of the furnace heater is 200 mm. 

Travel speed: 0.03-3 mm/hr   

Vacuum Pump (Not included)

10E-2 torr via dual-stage mechanical vacuum pump

10E-5 torr via Turbopump

The vacuum pump is optional.

For oxygen-sensitive material, suggest using recirculating gas purification system ( < 1 ppm) to replace turbopump

Dimension

Controller stage: 860mm L x 600mm W x 1220mm H

Furnace stage: 1170mm L X 910mm W X 2500mm H

Shipping Weight & Dimensions

1) 3225 lbs, 83x48x86"

2) 751 lbs, 49x41x58"

 

The crystal growth furnace is suitable for Bridgman method (crucible descent method), crystal growth under vacuum, protective atmosphere, or oxidizing atmosphere.

Crystal Growth furnaces are used to grow high-quality single crystals with uniform properties and low defect density.
