| description | A device for the production of silicon blocks comprises a vessel for receiving a silicon melt, the vessel comprising a vessel wall comprising at least one side wall and a bottom as well as an inside and an outside and a central longitudinal axis, and means for creating a temperature field on the inside of the bottom, the temperature field having a temperature gradient at the bottom of the vessel which is perpendicular to the central longitudinal axis at least in some regions when the silicon melt cools down for crystallization. |
