1650C max. Bridgman furnace for directional solidification of Polycrystalline Ingots with automatic crucible retrieving system
CY-SKJ-BG1650 is a 1650°C max. Bridgman furnace for directional solidification of Polycrystalline Ingots upto 37mm diamerter. Three individual controlled heating modules & speed adjustable cooling fans at furance 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.
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;
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 enable an automatic and convenient sample loading / retrieving;
220VAC single phase 50/60Hz
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
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
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;
Three PID temp. controller with 30 programmable segments for precise control of heating, cooling rate and dwell time.
European Temperature controller, with +/- 0.1 ºC temperature accuracy.
Three B type thermocouples (one for each zone).
One 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.
