The object of the invention are solutions of alkali metal amides MNRR, wherein M is an alkali metal selected from Li, Na, K, Rb, Cs; Rand Rindependently of one another are linear, branched or cyclic alkyl groups having 1 to 8 C atoms or together are a cycloalkyl radical, the alkali metal amides being present in methyltetrahydropyran or in a solvent mixture containing methyltetrahydropyran, and processes for their preparation.

Stable alkali amide solutions and processes for preparing same

The invention relates to a process for the production of lithium metal and lithium alloy mouldings, wherein solutions of metallic lithium in ammonia having the composition Li(NH)and n=0-10 are brought into contact with metallic or electronically conductive deposition substrates and the ammonia is removed at temperatures of −100 to 100° C. by overflowing with inert gas or at pressures of 0.001 to 700 mbar, so that the remaining lithium is deposited on the deposition substrate or/and it is doped with lithium or alloyed by it.

The invention relates to a novel process for preparing lithium sulfide and to the use thereof, wherein a reaction of lithium-containing strong bases with hydrogen sulfide is undertaken in an aprotic organic solvent within the temperature range from &#x2212;20 to 120&#xb0; C. under inert conditions. The lithium sulfide obtained by the process is used as a positive material in a galvanic element or for the synthesis of Li ion-conductive solids, especially for the synthesis of glasses, glass ceramics or crystalline products.
