ABSTRACT:
A crystal growing apparatus includes a crucible, a feed pipe and a pulling mechanism. The crucible serves to melt a crystalline material. The feed pipe serves to cause the crystalline material to fall into the crucible to charge the crucible with the crystalline material. The pulling mechanism serves to pull a single-crystal from the molten material in the crucible. The feed pipe has a lower end positioned slightly above the surface of the molten material in the crucible and including a plurality of baffle plates mounted on an inner peripheral wall thereof in longitudinally spaced relation to one another. The baffle plates are arranged so that a pitch defined between adjacent two baffle plates decreases toward the lower end of the feed pipe.
