Product Application Of Lithium hydride CAS#7580-67-8

Lithium hydride is a bluish-white crystal that is flammable in moisture. Used as a source of hydrogen gas that is liberated when LiH becomes wet. LiH is an excellent desiccant and reducing agent as well as a shield that protects from radiation created by nuclear reactions.
