ABSTRACT:
A large polycrystalline body of a 2,6 or 3,5 volatile compound is produced in a graphite crucible under low external pressure by passing a narrow molten zone through a charge of the compound contained in the graphite crucible the interior of which is coated with pyrolytic graphite. By a similar technique, but by use of a hot zone cooler then the molten zone, the polycrystalline body is converted to a monocrystalline body.
