OBSERVATIONS ON THE GROWTH OF ALPHA-IRON SINGLE CRYSTALS BY HALOGEN REDUCTION
Abstract
By increasing the scale of the conventional technique for growing Fe whiskers, single crystals were produced of alpha-iron 1 to 2 mm in diameter and up to 80 mm in length. Reduction of molten FeCl2 by H at 731 C was employed. Approximately 0.6 kg FeCl2.4H2O was used; to insure that all Cl was reduced and all HCl was removed from the system, the reaction time was 12 hrs. Most of the crystals grown according to this technique were considerably longer and thicker than those obtained by the use of a smaller amount of salt under the same operating conditions. Such crystals represent a reproducible source of high purity, single crystals of alpha-iron of reasonable experimental size, conveniently preoriented by growth.
