A transmitting unit, to an energy transfer system and to a method for operating at least one of the aforementioned apparatuses.

Abstract: A device for producing a target material from starting material comprises a chamber, at least one trough, at least a first heating element being configured to heat the chamber such that starting material is vaporized, and at least one collecting vessel being configured to receive a condensate that will constitute the target material. The device optionally comprises at least a first source of negative pressure or at least a first supply device being in connection with the chamber being configured to evacuate the chamber or to supply an inert gas to the chamber. The device further comprises at least one condensation device, wherein said condensation device is configured to condensate the vaporized starting material, whereby the condensate is formed, and/or at least a first gate device being in connection with the chamber such, that the starting material is introducible into the chamber via said first gate device.

Abstract: A process for producing high-purity magnesium by means of distillation at reduced pressure, characterized in that, the high-purity magnesium condenses in the liquid state, whereby the starting material in the form of a magnesium-containing melt is present together with the upper region of a condensation vessel in the upper region of a retort, whereby the retort consist of a material that releases no volatile impurities into the magnesium steam, whereby the upper region of the retort is brought to a temperature above the boiling point of magnesium, within the limits of two level lines, and is then held constant, such that steam rises from the boiling magnesium-containing metal melt and fills the interior of the upper region of the retort, whereby the steam infiltrating the upper region of the condensation vessel condenses below the lower level line and collects as high-purity melt in the lower region of the condensation vessel, and whereby in order to prevent contaminated melt that drops from the region above

Abstract: A process for producing high-purity magnesium by distillation at reduced pressure, which includes providing an apparatus having a retort formed from a material inert with respect to magnesium and an upper region defined by two vertically spaced level lines, a condensation vessel having a lower region and an upper region extending into the upper region of the retort, wherein the retort and condensation vessel are coupled to one another by an opening arranged in the upper region of the condensation vessel; providing a magnesium-containing metal melt to the retort at a level below the gap; and heating and maintaining the upper region of the retort at a temperature above the boiling point of magnesium to fill the retort with steam, thereby delivering a high purity melt into the condensation vessel via the opening.

Abstract: A starting material 2 in the form of a magnesium-containing metal melt is present together with the upper region 32 of a condensation vessel 3 in the upper region 11 of a retort 1 heated by the external heating element 5, wherein the steam produced according to the arrows 91, according to arrow 92, enters the upper region 32 of the condensation vessel 3 through the opening 31 below the cover 4 which provides protection from unwanted ingress of contaminated magnesium melt, wherein said steam condenses in the lower region 12 of the retort which is heated by a second heating element 51, below the line 8 corresponding to the melting point isotherm of magnesium, to give the high-purity magnesium melt 21 in the lower region 33 of the condensation vessel 3.
