Abstract

In the production of a monocrystalline rod by the passage of a molten zone through a polycrystalline rod having a monocrystalline seed fused thereto, the molten zone is passed through the rod a number of times, e.g. 9, from the junction with the seed, whereafter the molten zone is passed through the rod from a point therein spaced from the junction with the seed, e.g. a distance equal to the diameter of the rod. The recrystallized rod may be cut from the seed at the said point, the rod stump then being used as seed in the production of a further monocrystalline rod by the method of the invention. The apparatus employed may be the same as described in Specification 915,881.
