Abstract

A device for producing a single crystal by crystallizing the single crystal in a melt zone, comprising a housing, an inductor for generating heat in the melt zone, a reheater which surrounds and applies thermal radiation to the crystallizing single crystal, and a separating bottom which delimits downward an intermediate space between the reheater and a wall of the housing at a lower end of the reheater.
