1650°C Bridgman Furnace for Directional Solidification and Crystal Growth

STA-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
