lithium hydride

[′lith·ē·əm ′hī‚drīd]
(inorganic chemistry)
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 Hydride


LiH; colorless crystals. Density, 0.776 g/cm3. It is the most stable of all the alkali and alkaline-earth metal hydrides. In a vacuum it melts at 680°-697°C, with virtually no decomposition; at higher temperatures it decomposes. It reacts vigorously with water: LiH + H2O = LiOH + H2. In industry it is prepared mainly by the hydrogenation of fused lithium with pure hydrogen at 680°-700°C. Lithium hydride is used for the direct and rapid production of hydrogen (1 kg LiH yields 2.8 m3 H2) and many metal hydrides and as a strong reducing agent in organic synthesis.

The generator design includes storage vessels for the lithium hydride slurry and a small amount of water, slurry and water pumps, mixing reactor, hint exchanger, and hydroxide storage tank.
Lithium hydride prepared as a slurry at centralized plants would be pumped into tanker trucks or pumped through pipes to distribution centers where it will be loaded into vehicles or carried to storage vessels in homes, business, or industry.
