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.

So, on an afternoon somewhere in the Pacific, in the year before my birth, Teller and his minions supervised the wrapping of a regular, atomic bomb in a casing of lithium deuteride.
As early as 1986, Soviet scientists reported observing neutron emission when they violently crushed lithium deuteride in the presence of an ice made of heavy (deuterium-containing) water.
