Lithium carbonate is White, light, alkaline powder.
It is an inorganic compound, the lithium salt of carbonate with the formula Li
2CO3. This white salt is widely used in the processing of metal oxides.
For the treatment of bipolar disorder, it is on the World Health Organization's List of
Essential Medicines, the most important medications needed in a basic health
system.

►Properties and reactions
Unlike sodium carbonate, which forms at least three hydrates, lithium carbonate
exists only in the anhydrous form.Its solubility in water is low relative to other lithium
salts. The isolation of lithium from aqueous extracts of lithium ores capitalizes on
this poor solubility. Its apparent solubility increases 10-fold under a mild pressure of
carbon dioxide; this effect is due to the formation of the metastable bicarbonate,
which is more soluble:
Li2CO3 + CO2 + H2O ⇌ 2 LiHCO3
The extraction of lithium carbonate at high pressures of CO2 and its precipitation
upon depressuring is the basis of the Quebec process.Lithium carbonate can also
be purified by exploiting its diminished solubility in hot water. Thus, heating a
saturated aqueous solution causes crystallization of Li
2CO3.Lithium carbonate, and other carbonates of group 1, do not decarboxylate
readily. Li2CO3 decomposes at temperatures around 1300 °C.
Adverse reactions
Extended use of lithium to treat various mental disorders has been known to lead to
acquired nephrogenic diabetes insipidus.
►Application
Lithium carbonate is an important industrial chemical. It forms low-melting fluxes
with silica and other materials.
1. Glasses derived from lithium carbonate are useful in ovenware.
2. Lithium carbonate is a common ingredient in both low-fire and high-fire ceramic
glaze.
3. Its alkaline properties are conducive to changing the state of metal oxide
colorants in glaze particularly red iron oxide (Fe2O3).
4. Cement sets more rapidly when prepared with lithium carbonate, and is useful for
tile adhesives.
5. When added to aluminium trifluoride, it forms LiF which gives a superior
electrolyte for the processing of aluminium.
6. It is also used in the manufacture of most lithium-ion battery cathodes, which are
made of lithium cobalt oxide.
