Continuous feeding device for large-diameter gallium antimonide crystal growth

A continuous feeding device for growth of large-diameter gallium antimonide crystals relates to the technical field of single crystal growth equipment and comprises a main furnace chamber and an auxiliary furnace chamber, two sets of movable melt crucible components are arranged in the main furnace chamber, each melt crucible component comprises a double-layer melt crucible, and the double-layer melt crucible is arranged in the auxiliary furnace chamber. The lifting movement and the horizontal movement of the double-layer melting crucible in the main furnace chamber are controlled through the mechanical arm controller; and an inserting plate sealing valve is arranged between the auxiliary furnace chamber and the main furnace chamber so as to control whether the auxiliary furnace chamber is communicated with the main furnace chamber or not. The invention designs a single crystal growth continuous feeding device with double chambers and two double-layer melting crucibles according to the problem that the loss r
