Abstract: A cold crucible usable in the field of high-temperature production of monocrystalline materials. The cold crucible includes: a cold cage which has sectors made of a material having good electrical conductivity and in which a charge is melted, and a cooling device with heat transfer fluid, configured to cool each segment of the cold cage from the inside. The cold crucible is essentially such that it further includes at least one device for generating a static magnetic field, each generating device being housed inside one of the sectors of the cold crucible. Each static magnetic field thus generated having the effect of slowing down the electromagnetic stirring of the molten charge, such that it is possible to produce monocrystalline ingots of significantly larger diameter than the diameter of the seed initiating their growth.

Abstract: A cold crucible having application in the field of making monocrystalline materials at high temperature. The cold crucible includes: a cold cage having sectors made of a good electrical conductor material and in which a charge is molten, and a cooling device with a heat-transfer fluid, configured so as to cool down, from inside, each segment of the cold cage. At least one sector of the cold crucible includes a housing and is removable, the housing being proper and intended to accommodate at least one so-called functionalising device of the cold crucible. Henceforth, it is possible to functionalise each sector independently of the others, by accommodating therein, a functionalising device configured, inter alia, so as to modify and/or analyse at least one property of the charge, in particular the molten charge, in the cold cage.

Abstract: A device used for a process of coating fibers with a metal by a liquid method is disclosed. In this process, a fiber is drawn through a bath of molten liquid metal so as to be coated with the molten liquid metal. The liquid metal bath is maintained in a crucible of the “levitation” type, which at least partly eliminates contact between the liquid metal and the crucible. The bath is fed with metal, during the process, by a metal powder.

Abstract: An induction furnace includes a crucible having a plurality of cooled metallic segments (6A, 6B) electrically insulated from each other and an electromagnetic induction coil (5) arranged around the crucible, wherein the electromagnetic induction coil is energized with low frequency electric current. Each of the metallic segments forming the crucible wall is made of a relatively thin sheet, and a cooling pipe is provided on each segment. The cooling pipes (22) are welded or brazed to an outer surface of each corresponding segment. A refrigerant flows through each pipe in order to evacuate heat from the corresponding segment. The furnace further includes a magnetic core (8) disposed above and near the top surface of the charge placed in the crucible. This magnetic core provides local narrowing of the magnetic field lines, causing centripetal motion of the melted part of charge located at or near the top surface of the charge.
