A method for the formation and treatment of crystals of a given material that is conductive at a temperature below its melting point, characterized by the operations comprising subjecting a germ of said material to heating by high frequency induction to cause it to melt a part of said germ while the rest is in the solid state, the eddy currents induced in the melted part interacting with the high frequency field to move the molten part, dissolve additional material in said molten part and remove said germ from the zone of heating by induction, to control the formation of the solid part thereof.
