Abstract

A charge for recrystallization is inserted in a tube; the remote region of the tube is heated until a steady temperature gradient is formed, a gas is introduced at below atmospheric pressure; the tube is sealed and the charge is quickly transferred to the hot region where it vaporizes and crystals are formed in the cold region. The crystals may be grown on a crystal or fibre. The growth of crystals on fibres is described in Specification 943,877.
