    Abstract: An electrolysis cell for preparing alkali metals from a liquid alkali metal heavy metal alloy, including a tube arranged essentially horizontally having a closure device at each of the two ends of the tube. At least one solid electrolyte tube arranged concentrically in the tube and oriented with openings towards one end of the tube such that a first annular gap for conducting a liquid alkali metal, which forms an anode, is present between the inside of the tube and the outside of the solid electrolyte tube. An interior space in the solid electrolyte tube, sealed off from an alloy inlet, first annular gap and an alloy outlet, accommodates liquid alkali metal that can be used as a cathode.

    Abstract: A solid polycrystalline potassium ion conductor having a .beta."-Al2O3 structure is obtain- able by means of ion exchange of the alkali metal ions of a polycrystalline alkali metal .beta."-Al2O3 moulding, in which the alkali metal ions are sodium ions or a mixture of sodium and potassium ions and the molar ratio M2O (M = alkali metal) to Al2O 3 is 1 : x, x being an integer or non-integer number within the range 5 to 11, for potassi um ions, the ion exchange being effected by a method wherein neither chloride-containing nor liquid potassium ion sources are used, the method comprising the steps of: embedding the polycrystalline alkali metal .beta."-Al2O3 moulding in an oxid ic powder containing potassium and aluminium of a molar K2O : Al2O3 ratio within the range of 1 : (x- 1) to 1 : (x+1), the weight of oxidic powder amounting to at least two times the weight of the moulding; heating the embedded moulding at a rate of at least 100.degree.C per hour to at least 1100.degree.C; and further heating to at least 1300.degree.C, this temperature being maintained for at least one hour prior to cooling. Potassium metal is obtained, starting from potassium amalgam, by electrolysi s using an anode containing potassium amalgam, liquid potassium metal as a cathode a nd this solid potassium ion conductor as a membrane separating cathode and anode spaces.

    Abstract: Lithium production from aqueous solution, by lithium amalgam formation and use as a moving anode in an electrolysis cell, is new. Metallic lithium is produced from an aqueous lithium salt solution by forming a lithium amalgam from the solution and using amalgam as a moving anode in an electrolysis cell containing a lithium ion conductive solid electrolyte and a molten lithium cathode. Preferred Features: The lithium amalgam anode is moved by stirring and/or pumping under atmospheric or slightly elevate pressure. The amalgam is produced by chlor-alkali electrolysis.
