Seed or a carrier is dipped into a supercooled melt or molten soln. and rotated and raised as required. The molten material is circulated during the growing period and is continuously removed from the surface of the growing crystal by centrifuge. Molten material is reheated and supercooled again before being returned to the surface of the growing crystal. Equipment used comprises a crucible to hold the molten material and is located on a support within a furnace. Single crystal or carrier is held in a support, which is attached to a rod. Single crystal seed or carrier is held at, or below, the surface of the molten material. Crucible is equipped with a divider cylinder, having perforationss (20). The top of the divider cylinder is arranged at 0.1-5 max. below the surface of the molten material.
