Lithium

Description

 

Lithium is a metal that belongs to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft, lithium batteries and lithium-ion batteries. Lithium niobate is used extensively in telecommunication products such as mobile phones and optical modulators, for such components as resonant crystals. Lithium is also used in the pharmaceutical and fine-chemical industry in the manufacture of organolithium reagents, which are used both as strong bases and as reagents for the formation of carbon-carbon bonds. Organolithium compounds are also used in polymer synthesis as catalysts/initiators in anionic polymerization of unfunctionalized olefins. Lithium compounds continue to be the gold standard for the treatment of bipolar disorder and are helpful for related diagnoses, such as schizoaffective disorder and cyclic major depression.
