    Abstract: Device for crucible-free zone melting a crystalline rod, particularly a semiconductor rod, includes two induction heating coils annularly surrounding the crystalline rod, and driving means for adjusting the position of the induction heating coils relative to one another in a direction transverse to the rod axis. Method of using the device includes relatively moving the induction heating coils away from one another transversely to the rod axis at the junction of a seed crystal with one end of the rod so as to fuse the seed crystal to the rod, relatively moving the induction heating coils on the one hand and the rod on the other hand along the axis of the rod and simultaneously relatively displacing the induction heating coils gradually toward one another in a direction transverse to the rod axis in conformity with an outwardly flaring conical portion of the rod extending from the seed crystal, until the induction heating coils substantially coaxially surround the main cylindrical portion of the rod.

    Abstract: Apparatus for producing monocrystals by potless zone melting, in which the monocrystal, setting out from a seed crystal, passes through a neck and a transitional zone into the main part of the monocrystal. A chamber is provided for the formation of a vacuum or a protective gas atmosphere plus a heating device for the production of the melting heat, driving means for the mechanical movements necessary for the crystal formation, a mounting for the seed crystal, and a supporting device which is applicable to the monocrystal beyond the neck, and a plurality of gripping bodies distributed about the circumference and applicable to the monocrystal radially on its substantially cylindrical surface the gripping bodies are disposed such that they first perform a radial approach to the monocrystal until a virtually force-free contact is made therewith, adapting themselves to the surface geometry and position of the monocrystal, whereupon the gripping force is increased and the gripping bodies are locked.
