Operation Instruction

Application Note
  • Warning: MoSi2 heating element is used in the high temperature under the oxidizing atmosphere, which not be used in the temperature between 400ºC and 700ºC for a long time, otherwise, the element will be cremated.
  • With option Crane with Winch and Mullite Round Single Bore Tubes,  you can DIY a vertical furnace with rapid heating and cooling function. ( click Pic 1 )
  • You can order a Tungsten wire or platinum tire to fabric your sample basket to fast cool after heating. (Molybdenum wire can not be used because of oxidation.)
  • We can help you to build a pulling and rotation module for top seed solution growth of a single crystal  ( click Pic 2 )
  • The furnace can be modified to be one vacuum crucible furnace with a vertical quartz liner and stainless steel vacuum flange. (click Pic 3)
