Lithium oxide is a chemical compound composed of lithium, and oxygen. It is used for the preparation of lithium niobate, as well as an additive in ceramics and glasses.

Production and representation

Lithium oxide can be produced by combustion of lithium or by thermal decomposition of lithium peroxide and lithium hydroxide.

Properties

Lithium oxide is a white, odorless solid. He has a crystal structure of the anti - fluorite - type (a = 4.611 Å). The standard enthalpy of formation of lithium oxide is ΔHf0 = -599.1 kJ / mol.

Use

Lithium oxide is used as a starting material for the manufacture of lithium niobate. Furthermore, it may be used as additive for the production of ceramics and glasses. In fusion reactors, it can be used.
