CRUCIBLE RECOVERING METHOD AND APPARATUS THEREFOR

摘要

A method and apparatus for recovering the inner crucible used in a double crucible process of drawing-up a single crystal. The inner crucible is recovered by pulling up the inner crucible above the molten raw material using only a simply arranged jig which does not require reconstruction of the vessel accommodating the single crystal drawing-up system. The arrangement is such that the inner crucible is allowed to rotate during the period in which the single crystal is being grown.
