Lithium Carbonate BP
Abstract:
Lithium carbonate is an inorganic compound, the lithium salt of carbonate with the formula Li2CO3. This white salt is widely used in the processing of metal oxides.
Uses/Applications:
It forms low-melting fluxes with silica and other materials. Glasses derived from lithium carbonate are useful in ovenware. Lithium carbonate is a common ingredient in both low-fire and high-fire ceramic glaze. It is also used in the manufacture of most lithium-ion battery cathodes, which are made of lithium cobalt oxide.
