Product Description

1500ºC Bridgman Furnace for Directional Solidification of Polycrystalline Ingots - EQ-SKJ-BG1500
Introduction of bridgman furnace for directional solidification

EQ-SKJ-BG1500 is a 1500°C max. Bridgman furnace for directional solidification of Polycrystalline
Ingots upto 1'' diameter. Three individual controlled heating modules & speed adjustable cooling
fans at furnace exit provide advantages to create larger temp. gradient at the melt/crystal interface
as needed. Automatic crucible retrieving system enables the most convenient way for sample loading/unloading.

Technical parameter of bridgman furnace for directional solidification
 

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 the better control over the temperature gradient at the melt/crystal interface;  φ25mm 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 enable an automatic and convenient sample loading / retrieving; The use of 2'' O.D mullite tube provides better thermoshock resistance upto 1500C when larger thermogradient is desired
Power Requirements	220VAC Three phase 50/60Hz 14KW
Max,  Working Temperature	1500°C -  SiC heating elements
Processing Tube & Flange	Mullite (60% Al2O3 +38% SiO2) Tube, Size: 50.4 mm OD  x 44.5 mm ID x 1200 mm L A pair of 2'' 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	φ25X20mm 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 PID temp. controller with 30 programmable segments for precise control of heating, cooling rate and dwell time. Built-in overheating & broken thermocouple protection. +/- 2 ºC temperature accuracy. Three B type thermocouples (one for each zone). Temperature gradient along the length of heated area < 7.5ºC/mm Heating & Cooling rate: <10ºC/mm
Cooling Fans	Two 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 360 mm.  Travel speed: 0.15-15 mm/hr
Vacuum Pump (Not included)	10E-2 torr via dual stage mechanical vacuum pump 10E-5 torr via Turbo pump
Dimension	1080mm L X 880mm W X2980mm H
Shipping Weight	2500Lbs
