A STUDY OF THE GROWTH AND PERFECTION OF SINGLE CRYSTALS OF THE RARE EARTHS AND ALKALI METALS.
Abstract
Single crystals of sodium and potassium were prepared by the Czochralski techniques in glass vessels under vacuum or an argon atmosphere. Methods of cutting, orienting, and studying the samples microscopically were developed. Chlori nated hydrocarbons show considerable promise as etchants. An arc-image furnace was constructed and single crystals of nickel were prepared. The major problem in the use of this furnace is temperature control. (Author)
