Abstract: Apparatus for crucible-free zone melting a rod-shaped member of crystalline material includes at least one heating device for heating a first portion of the rod-shaped member to the melting point thereof so as to form a melting zone therein, and another heating device for afterheating a second portion of the rodshaped member directly adjacent to the melting zone and recrystallized therefrom, the other heating device comprising a ring-shaped heat radiator surrounding the portion of the rodshaped member adjacent the melting zone, the radiator being heatable to a temperature nearly equal to the melting temperature of the crystalline material.
