Lithium Oxide Powder Description

Lithium Oxide powder is a highly insoluble thermally stable Lithium source suitable for glass, optic, and ceramic applications. Lithium oxide is a white solid also known as lithia, it is produced when lithium metal burns in the presence of oxygen. 

Lithium oxide (Li2O) or lithia is an inorganic chemical compound. It is a white solid. Although not specifically important, many materials are assessed on the basis of their Li2O content. For example, the Li2O content of the principal lithium mineral spodumene (LiAlSi2O6) is 8.03%.
