The Apparatus and Technique for Growing Large Specimens of Single Crystal Zinc

Abstract

The apparatus and technique are described for the growth of large, strain‐free, single crystals of zinc of any desired orientation. It is shown that a gross mosaic structure may occur in the beginning of the growth of a crystal but may be eliminated by a steep temperature gradient. The data show the necessity of satisfying certain growth conditions, namely, that the ratio of the temperature gradient to the rate of growth must be near a certain favorable, but not necessarily the same, value for each orientation.
