Lithium carbonate
Summary
Lithium carbonate is an inorganic compound, the lithium salt of carbonic acid with the formula Li2CO3. This white salt is widely used in processing metal oxides. It is on the World Health Organization's List of Essential Medicines for its efficacy in the treatment of mood disorders such as bipolar disorder.
Lithium carbonate is an important industrial chemical. Its main use is as a precursor to compounds used in lithium-ion batteries.
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 forms low-melting fluxes with silica and other materials. Its alkaline properties are conducive to changing the state of metal oxide colorants in glaze, particularly red iron oxide (Fe2O3). Cement sets more rapidly when prepared with lithium carbonate, and is useful for tile adhesives. When added to aluminium trifluoride, it forms LiF which yields a superior electrolyte for the processing of aluminium.
Lithium carbonate-derived compounds are crucial to lithium-ion batteries. Lithium carbonate may be converted into lithium hydroxide as an intermediate. In practice, two components of the battery are made with lithium compounds: the cathode and the electrolyte.
The electrolyte is a solution of lithium hexafluorophosphate, while the cathode uses one of several lithiated structures, the most popular of which are lithium cobalt oxide and lithium iron phosphate.
Lithium (medication)
In 1843, lithium carbonate was used to treat stones in the bladder. In 1859, some doctors recommended a therapy with lithium salts for a number of ailments, including gout, urinary calculi, rheumatism, mania, depression, and headache.
In 1948, John Cade discovered the anti-manic effects of lithium ions. This finding led to lithium carbonate's use as a psychiatric medication to treat mania, the elevated phase of bipolar disorder. Prescription lithium carbonate from a pharmacy is suitable for use as medicine in humans but industrial lithium carbonate is not since it may contain unsafe levels of toxic heavy metals or other toxicants.
