Lithium hydride
LiH, flammable, brittle, white translucent crystals; decomposes in water; insoluble in ether, benzene, and toluene; used as a hydrogen source and desiccant, and to prepare lithium amide and double hydrides.
Lithium hydroxide
LiOH; LiOH.H2O. colourless crystals; used as a storage-battery electrolyte, as a carbon dioxide absorbent, and in lubricating greases and ceramics.
|
Lithium iodide
LiI; LiI.3H2O, white, water-and alcohol-soluble crystals; Lil metls at 4460C; Lil.3H2O loses water at 720C; used in medicine, photography, and mineral waters.
Lithium molybdate
Li2MoO4, water-soluble white crystals melting at 7050C; used as a catalytic cracking (petroleum) catalyst and as a (petroleum) catalyst and as a mill additive for steel.
|
Lithium nitrate
LiNO3, water-and alcohol-soluble colourless powder melting at 2610C; used as a heat-exchange medium and in ceramics, pyrotechhics, salt baths, and refrigeration sustems.
Lithium perchlorate
LiCIO4.3H2O, a compound with high oxygen content (60% available oxygen), used as a source of oxygen in rockets and missiles.

|
Lithium stearate
LiC18H35O2, a white, crystal line compound with a melting point of 220C; used in cosmetics, plastics, and greases, and as a corrosion inhibitor in petroleum.
Lithium sulphate
(Li2SO4), a white solid which is obtained by the addition of excess lithium oxide or carbonate to a solution of sulphuric acid. It is readily soluble in water from which it crystallizes as the monohydrate.

Lithium tetraborate
Li2B4.5H2O, white crystals that lose water at 2000C; insoluble in alcohol, soluble in water; used in ceramics.
Lithium titanate
Li2TiO3, a water-insoluble white powder with strong fluxing ability when used in titanium-containing enamels; also used as a mill additive in vitreous and semivitreous glazes.

Lophine
C21H16O2, a colourless, crystalline, water-insoluble compound that melts at 2750C; used as an indicator in fluorescent neutralization tests.
Lutetium, Lu
At.no. 71, at.wt. 174.967, m.p. 16560C, b.p. 33150C, d 9.84. The least of the lanthanide (4f) elements. The metal is hcp. After neutron irradiation Lu nuclides emit pure b radiation which can be used in cracking, polymerization and other catalytic process.
Magenesium halide
A compound formed from the metal magnesium and any of the halide elements; an example is magnesium bromide.
Magnalium
Trade name for an aluminium based alloy of high reflectivity for light and ultraviolet radiation that is having 1-2% of copper and between 5% and 30% of magnesium. Strong and light, these alloys also sometimes have other elements, such as tin, lead, and nickel.
Magnesia
It is magnesium oxide, MgO.
Magnesite
Refers to a white, colourless, or grey mineral form of magnesium carbonate, MgCO3, crystallizing in the trigonal system. It could be formed as a replacement mineral of magnesium-rich rocks when carbon dioxide is available. Magnesite is mined both as a source of magnesium carbonate.
Magnesium
A light metallic element; the second member of group II of the periodic table (the alkaline earths). It has the electronic configuration of neon with two additional outer 3s electrons. The element accounts for 2.09% of the Earth’s crust and is eighth in order of abundance. It occurring a wide variety of minerals such as brucite (Mg(OH)2), Carnallite (MgSO4.7H2O), magnesite (MgCO3), and dolomite (MgCO3.CaCO3); and also as MgCl2 in sea water. The metal is obtained by several routes, depending on the mineral used, but all leading to the chloride, followed by electrolysis of the fused chloride.
