A method for the production of lithium oxide and the use of such lithium oxide is described herein. The method includes reacting lithium carbonate with elemental carbon or a carbon source forming elemental carbon under certain reaction conditions. The reaction may be carried out in containers whose product-contacting surfaces are corrosion resistant to the reactants and products. The lithium oxide obtained according to the method described herein can used for the production of pure lithium hydroxide solutions or for the production of glasses glass ceramics or crystalline ceramics, for example, lithium ion conductive ceramics.

Method for producing lithium oxide

The invention relates to a method for producing aprotic solutions that contain zinc bromide and lithium bromide, the reaction of the reactants to the product being carried out as a one-pot reaction.

An organomagnesium synthesis agent, a process for preparing this synthesis agent, and its use.

Organomagnesium synthesis agent

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.
