Top seed solution growth furnace (Tssg) for growing various single crystals via flux solution. The box furnace uses alumina fiber as the furnace chamber material and MoSi2 as the heating element. Its chamber size is φ330mm × 250mm (H), and the maximum temperature can reach 1700 ℃. 30-segment programmable precision temperature controller, which can set heating and cooling temperature program according to different customer needs, the temperature control accuracy can reach ± 1 ℃, equipped with a precision pulling and rotation mechanism can be used to grow various crystal materials via top seed crystal flux solution, pulling speed and rotation speed can be customized according to customer needs.
Then, this paper puts forward a process prediction system of crystal growth using TSSGmethod which is based on the finite element simulation technology. With friendly interface,this process prediction system allows FETSSG’s numerical results to be indexed, filed andstored, etc. TSSG method crystal growth process prediction system can provide instant datawhich is of guidance value in a series of research in the laboratory.
