Questions And Answer | Back Directory | [Description]
Lithium carbonate (molecular structure is Li2CO3, English name is lithium carbonate) as a colorless monoclinic crystal or white powder. Density is 2.11. Melting point is 618 ℃. Without deliquescence, it is stable in the air. Low solubility in water, the solubility decreases with increasing temperature. Solubility in cold water is greater than hot water. It is Soluble in dilute acid, insoluble in alcohol and acetone. Carbon dioxide is introduced into the aqueous suspension of lithium carbonate, lithium carbonate is converted to lithium acid carbonate and dissolved. If the solution of lithium acid carbonate is heated and then it releases carbon dioxide and precipitates lithium carbonate. The nature of the lithium carbonate may be used to remove impurities from lithium carbonate. Since lithium ion has a strong polarizability, thus thermal stability of lithium carbonate is worse than other alkali metal carbonate, when heated to above the melting point, it will decompose to produce carbon dioxide and lithium oxide.
| [Chemical Properties]
Lithium carbonate is a white monoclinic crystalline solid. Typically for carbonates, lithium carbonate reacts with acids stronger than carbon dioxide or carbonic acid to yield the lithium salt of the acid and carbon dioxide. The reactions may be carried out in a solution, as an aqueous slurry, or, less effectively, with solid lithium carbonate.
Lithium carbonate exhibits a low water solubility for an alkali metal carbonate. The solubility decreases with increasing temperature. It is not hygroscopic and is generally stable when exposed to the atmosphere. In fact, it is the normal end compound encountered when many basic lithium compounds are exposed to the atmosphere. Lithium carbonate may be dissolved in water by conversion to the hydrogen carbonate. Releasing carbon dioxide by heating the solution of lithium hydrogen carbonate causes reprecipitation of the lithium carbonate.
| [Uses]
The lithium carbonate industry is a global high monopoly industry, the current production capacity is mainly concentrated in three foreign manufacturers of SQM, FMC, Chemetall and so on.
Industrial lithium carbonate is used in the manufacture of other lithium salts, such as lithium chloride and lithium bromide and so on. It also acts as lithium oxide materials in enamel, glass, pottery and porcelain enamel, and it is also added to the electrolytic cell for electrolysis of aluminum to increase the current efficiency and reduce the internal resistance of the cell and the bath temperature. In medicine, it is mainly used for the treatment of mania, can improve their emotional disorders for schizophrenia. It has the effect of elevating peripheral leukocytes; can be used for synthetic rubber, dyes, semiconductor and military defense industry and so on; for the production of lithium tantalate, lithium niobate and other acoustic grade single crystal, optical grade monocrystalline etc; for preparation of the acoustic grade single crystal.
Battery grade lithium carbonate is mainly used for the preparation of lithium cobalt oxide, lithium manganese oxide, ternary materials, lithium iron phosphate and other lithium ion battery cathode materials; used in a matrix modifier; as aneuroprotective effect of lithium carbonate in amyotrophic lateral sclerosis.
| [Toxicity]
Lithium carbonate has a significant stimulating effect, firstly has damage on the gastrointestinal tract, kidney and central nervous system. Toxicity order of lithium compounds is Li <LiCl <Li2CO3, maximum allowable concentration: Lithium condensation and fragmentation aerosol were 0.05 mg/m3 and 0.5 mg/m3.
Wear rubber gloves and protective masks when working, in order to protect the respiratory organs against dust.
| [Preparation]
Lithium carbonate is obtained as an intermediate product in recovery of lithium metal from its ore, spodumene (See Lithium). It is prepared by mixing a hot and concentrated solution of sodium carbonate with lithium chloride or sulfate solution.
Li2SO4+ Na2CO3→Li2CO3+ Na2SO4 | [Reactions]
Lithium carbonate reacts with dilute acids, liberating carbon dioxide:
Li2CO3+ HCl →LiCl + CO2+ H2O
Thermal decompostion yields lithium oxide and carbon dioxide:
Li2CO3 → Li2O + CO2
Reaction with lime produces lithium hydroxide:
Li2CO3+ Ca(OH)2→2LiOH + CaCO3
The carbonate reacts with molten aluminum fluoride converting to lithium fluoride:
3Li2CO3+ 2AlF3 → 6LiF + 3CO2+ Al2O3
It combines with carbon dioxide in aqueous slurry forming soluble bicarbonate, which decomposes to carbonate upon heating:
Li2CO3+ CO2+ H2O →2LiHCO3
The bicarbonate can not be separated in solid form. It exists only in solution when carbonate dissolves in water saturated with CO2under pressure.

lithium carbonate: A white solid,Li2CO3; r.d. 2.11; m.p. 723°C; decomposesabove 1310°C. It is producedcommercially by treating the ore with sulphuric acid at 250°C andleaching the product to give a solutionof lithium sulphate.

It is also usedindustrially in ceramic glazes. | [Indications]
Lithium inhibits thyroidal incorporation of I- into Tg, as
well as the secretion of thyroid hormones, but it does
not inhibit the activity of the Na+-I- symporter or the
accumulation of I- within the thyroid. Lithium offers no
particular advantage over drugs of the thionamide class
but may be employed for temporary control of thyrotoxicosis
in patients who are allergic to both thionamides
and iodide. | [Brand name]

Drowsiness, dizziness, tiredness, increased thirst, increased frequency of urination, weight gain, and mildly shaking hands (fine tremor) may occur. These should go away as your body adjusts to the medication.
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
