Abstract

In the conversion of a polycrystalline rod <PICT:0932504/III/1> into monocrystalline form by zone-melting with the aid of a seed crystal, a polycrystalline rod 14 is supported, during its p passage through the heating zone, by a rigid refractory tube 12 having a compressible refractory liner 18. The rod may be of germanium or silicon. The tube may be of quartz and may be in semi-cylindrical sections. The liner may be of paper, woven material, or felt made from quartz fibres in the form of a sleeve or one or more layers of tape. Resistance or induction heating may be employed. Operation may be effected continuously by passing the polycrystalline rod and support through a guide tube at the heating zone by means of pairs of guide rollers (Fig. 2, not shown) and periodically adding additional sections of polycrystalline rod and support.
