Abstract

A die for drawing crystals from a molten bath, has a body bored with at least one longitudinal capillary channel arranged between a lower face of the body. The die is intended to be immersed in the molten bath and an upper face of the body intended to support the liquid coming from the molten bath through the capillary channel. The die upper face has a flat surface onto which the capillary channel emerges, and this flat surface forms an angle .theta. less than 90.degree. with the longitudinal axis of the capillary channel.
