  • Method for the crystallogenesis of a material electrically conducting in the molten state
    Patent number: 9493889
    Abstract: The disclosure 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 the material in a crucible, 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; the method including that the electromagnetic kneading is obtained by applying an alternating magnetic field. The disclosure also relates to a device for implementing the method.
