The largest use of lithium metal is in the production of organometallic alkyl and aryl lithium compounds by reaction of lithium dispersions with the corresponding organohalides.
Lithium metal is becoming increasingly important as an alloying component; it is also used as a deoxidizing and desulfurizing agent, especially for copper, nickel, and alloy steels.
In production of organometallic alkyl and aryl lithium compounds; in production of high-strength, low-density aluminium alloys for the aircraft industry; extremely tough, low-density alloys with aluminum and magnesium used for armor plate and aerospace components. In polymerization catalysts for the polyolefin plastics industry; manufacture of high-strength glass and glass-ceramics. As anode in electrochemical cells and batteries; as chemical intermediate in organic syntheses. Lithium stearate as thickener and gelling agent to transform oils into lubricating greases.
