Abstract
<PICT:0915881/III/1> In the production of a monocrystalline rod, e.g. of silicon, by the passage of a molten zone a plurality of times through a polycrystalline rod having a monocrystalline rod fused thereto, one of the passes starts from a point in the seed and subsequent passes start from the point of fusion, with the optional exception of the last, which may start from within the rod. The pass starting from within the seed may be in the first four and is preferably the second at a distance of at least 2 cm. from the point of fusion. As shown, a seed 11 is held in a rotatable ceramic cylinder 14 by means of a number of resilient molybdenum strips 13 and a molten zone is formed by a water-cooled pancake coil 18. Specification 915,882 is referred to.
