1650C Bridgman Furnace for Directional Solidification and Crystal Growth system

This 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.

In contrast to other Bridgeman systems, it keeps the melt stationary while moving the furnace up to control the temperature gradient, ensuring the stability of the growth interface.


Specification

Advanced Features

Three 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 convenientsample loading/retrieving.

Power Requirements

220V 50/60Hz

9.5KW

Working Temperature 

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

Continuous Operating Temperature: 1600°C

Heating Element

Silicon molybdenum rod

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

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

Warranty

One-year limited warranty.

Dimension

Controller stage:860mmL×600mmW×1220mmH

Furnace stage:1170mmL×910mmW×2500mmH


Optional:For single crystal growth,the rotation of the crucible stage is needed,an additional cost will apply.Please touch with our engineering team for more information.
