EQ-SKJ-BG1650 is a 1650°C max. Bridgman furnace for directional solidification of Polycrystalline Ingots up to 37mm diameter. Three individual controlled
heating modules & speed adjustable cooling fans at furnace exit provide advantages to creating larger temp. the gradient at the melt/crystal interface as needed.
Automatic crucible retrieving system enables the most convenient way for sample loading/unloading.
 Optional crucible rotation stage can be added at additional
cost for single crystal ingot growth. 




Basic Specifications:



    Advanced Features


     

  •      •  Three stacked heating modules with independent temperature measurement and control enable the
             flexibility of creating various temperature gradients along the length of the heated area;
  •      •  Two-speed adjustable cooling fans with TC at the exit of the furnace allow better control over the
             temperature gradient at the melt/crystal interface;
  •      •  φ42mm Alumina sample pulling stage with TC attachment for accurate temperature monitoring of the
            crucible on top and generate instant temperature plot;
  •      •  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: 1650°C ( <1hr)
  •      •  Continuous Operating Temperature: 1600°C


   Processing Tube &
   Flange

  •      •  High purity alumina furnace tube, Size: φ80mm O.D. 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 Retriving
   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, please click bottom left picture for more size info;
  •      •  100mm long for each zone, please click bottom right picture for more size info;

                     


   Temperature Control

     


  •      •  Three PID temp. controller with 30 programmable segments for precise control of heating, cooling
            rate and dwell time.
  •      •  Built-in overheating & broken thermocouple protection.
  •      •  European Temperature controller, with +/- 0.1 ºC temperature accuracy.
  •      •  Three B type thermocouples (one for each zone).
   Cooling FansOne speed adjutable 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 (bottom right picture)
  •      •  10E-5 torr via Turbopump (bottom left picture)
  •      •  The vacuum pump is optional. Please click here to choose a vacuum pump.
