• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema.
• Physical properties: White crystalline solid; cubic crystals; density 0.82 g/cm3; melts at 686.4°C; decomposes in water; soluble in acids.
• Uses: Lithium hydride is used in the manufactureof lithium aluminum hydride and silane, as apowerful reducing agent, as a condensationagent in organic synthesis, as a portablesource of hydrogen, and as a lightweight nuclear shielding material. It is now beingused for storing thermal energy for spacepower systems (Morris et al. 1988). 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. ▼▲ Industry Application Role/benefit Hydrogen Hydrogen storage Storage material/has the highest hydrogen content of any hydride Hydrogen preparation Hydrogen source/reacts violently with water to yield hydrogen Nuclear Nuclear reactors Neutron shield material Thermonuclear weapons Fusion fuel (lithium-6 deuteride) Astronomy Rocket fuel Excellent thermal value Organic chemistry Synthesis of complex metal hydrides Raw material Preparation of LiAlH4,LiBH4 and LiBHET3 ,etc. Preparation of other hydrides amides and 2H isotopic compound Reducing agent

Technology Process of Lithium

There total 8 articles about Lithium which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:
