Abstract
A charging material made from semiconductor material, is used for charging or recharging a melting crucible during the Czochralski crucible-pulling process. This charging material has a polycrystalline semiconductor rod, which at one end has a groove, and a monocrystalline semiconductor rod, which at one end has a tongue, which rods are coupled by means of a tongue-and-groove connection. There is also a holding system for holding a polycrystalline silicon rod during the Czochralski crucible-pulling process or the float zone process, which has a tongue-and-groove connection between the polycrystalline semiconductor rod, which at one end has a groove, and a monocrystalline semiconductor rod, which at one end has a tongue.
