Abstract

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.
