METHOD FOR THE CRYSTALLOGENESIS OF A MATERIAL ELECTRICALLY CONDUCTING AT THE MOLTEN STATE

摘要

The invention relates to a method for the crystallogenesis of a material that is electrically conducting at the molten state, by drawing from a molten mass of said material in a crucible (1), that comprises: progressively subjecting the molten material to a decreasing temperature so that a liquid-solid interface is formed; controlling the flatness of the liquid-solid interface of the material; subjecting the molten material, before and during solidification, to an electromagnetic kneading; said method being characterised in that the electromagnetic kneading is obtained by applying an alternating magnetic field. The invention also relates to a device for implementing said method.
