摘要
A multiple crucible crystal growing system using a temperature gradient method is disclosed. The system comprises a crystal furnace, a plurality of crucibles, and an elevating device, wherein the furnace includes a furnace body, a heater, and a hearth, wherein the furnace body from outer to inner includes an outer shell, a fiber insulation layer, an insulation brick layer, and a refractory layer. The height of the refractory layer is ⅔-⅚ of the height of the hearth, and the heater is located at ¼-½ of the height of the hearth. The hearth is in rectangular shape and able to hold multiple crucibles to grow crystals simultaneously. The present invention ensures doping concentration and uniformity. Therefore, it can be widely applied in the area of crystal growth.
