Lithium Hydride

Lithium Hydride

[Molecular Formula]      LiH
[CAS No.]    7580-67-8
[Product Description] 
Lithium hydride (LiH) is the compound of lithium and hydrogen. It is a colourless crystalline solid, although commercial samples appear gray. Characteristic of a salt-like, or ionic, hydride, it has a high melting point of 689 °C (1272 °F). 
Its density is 780 kilograms per cubic metre. It has a standard heat capacity of 29.73 J/mol.K with thermal conductivity that varies with composition and pressure (from at least 10 to 5 W/m.K at 400 K) and decreases with temperature.
It is a flammable solid and very reactive with water, producing the corrosive compound lithium hydroxide as well as hydrogen.

[Application] 
LiH has numerous uses:
·as a desiccant; 
·as a precursor for the synthesis of lithium aluminium hydride (LAH); 
in hydrogen generators; 
·as both a coolant and shielding in nuclear reactors; and in the manufacture of ceramics.
[Safety] 
LiH is flammable in air, and it reacts explosively with water to give corrosive LiOH together with hydrogen gas.
