Lithium is a soft, the lightest, silver-white, highly reactive metallic element in Group 1 of periodic table; atomic number 3; atomic mass 6.941; melting point ca 180.5 C; boiling point ca 1,342 C; specific gravity 0.534 g/cm³ valence +1; electronic config. 2-1 or 1s ²2s ¹. Lithium metal is prepared by the electrolysis of a molten mixture of potassium and lithium chlorides. It is used in various alloys with magnesium, copper, manganese, cadmium and aluminum to form a strong, low density material, as a heat transfer medium, in cooling system of nuclear reactor, and as a scavenger, in ceramics, glasses and in rocket fuel. Lithium forms many important inorganic and organic compounds such as;

Lithium Hydroxide (LiOH); white, hygroscopic, crystalline material; soluble in water, slightly soluble in ethanol and insoluble in ether; there are commercially forms of monohydrate and anhydrous; used for purification of gases and air (as a carbon dioxide absorbent), as a heat transfer medium, as a storage-battery electrolyte, as a catalyst for polymerization, in ceramics, manufacturing other lithium compounds and esterfication specially for lithium stearate which is used as general purpose lubricating greases due to its high resistance to water and the useful at both high and low temperature.

Lithium Carbonate (Li₂CO₃) ; white granular powder; slight soluble in water, melts at 723°C, decomposes above 1310°C; It is prepared commercially by treating the ore with sulphuric acid at 250°C and leaching the product to give a solution of lithium sulphate. The carbonate is then obtained by precipitation with sodium carbonate solution; It is used as a flux in the aluminium, glass and ceramics production to improves the brightness of glazes and increases the firing range. It is a source of lithia, strong high temperature flux. It is used as an additive in cement industry to improve acceleration and fast setting process. It is used as an additive in floor screeds and tiles. It is used for the production of other lithium chemicals and organic compounds as a catalyst. Pharmaceutical grade of lithium carbonate is used for the primary treatment of depression and bipolar disorder.

Lithium chloride; white hygroscopic deliquescent granule or powder having high melting point  at 614°C. Lithium chloride and bromide are the mostly proscopic materials used as a operating medium for air-conditioning and industrial drying system. It is used as brazing and welding fluxes. It is also used in as an intermediate for manufacturing other chemical compounds.

Lithium Fluoride  (LiF); white poisonous powder melting at 870°C, boiling at 1670°C; slightly soluble in water, soluble in acids but insoluble in alcohol; t is used as a flux in the aluminium, glass and ceramics production to improves the brightness of glazes and increases the firing range. It is used as a flux for brazing and welding of zirconium, titanium and magnesium. It is used as a heat-exchange medium.

Lithium Iodide  (LiI; LiI.3H₂O) white to yellowish solid; soluble in water alcohol; there are commercially anhydrous form (melts at 446°C) and trihydrate form ( loses water at 72°C); It is used in organic synthesis, manufacturing medicines and mineral waters.

Lithium Molybdate  (Li₂MoO₄); white crystals melting at 705°C; soluble in water; used as a catalyst for petroleum cracking and as a mill additive for steel.

Lithia (Li₂O); A white crystalline compound, melting at 1700°C. the main uses are in lubricating greases, ceramics, glass and refractories, and as a flux in brazing and welding.

Lithium Carbide (Li₂C₂);

Lithium Phosphate (Li₃PO₄);

Lithium Tetrahydridoaluminate (Lithal, LiAlH4); A powerful reducing agent in synthetic organic chemistry; aldehydes, esters and ketones to the corresponding alcohols. nitriles to primary amines.
