Producing a single crystal (1) by zone floating, comprises crystallizing the single crystal using an induction heating coil under a melting zone at a crystallization boundary (2), hindering the emission of crystallization heat by a reflector surrounding the single crystal. The single crystal is heated in a region of an outer edge of the crystallization boundary in a first zone using a heating device (6), during which a distance between an outer triple point at the outer edge of the crystallization boundary, and a center of the crystallization boundary is affected. An independent claim is also included for an apparatus for producing the single crystal by zone floating, comprising a reflector surrounding the single crystal, and a heating device for heating the single crystal. |
