General description

Lithium hydride is a simple neutral heteropolar diatomic molecule. It liberates hydrogen upon heating it to temperatures above 500oC. Lithium hydride, like lithium aluminum hydride, exhibits a high gravimetric hydrogen storage capacity. LiH is known to have large specific heat and latent heat of fusion.5
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Lithium hydride may be used as an effective neutron shield for mobile nuclear reactors. LiH may also be used as a rocket fuel, energy storage system, and heat shield.5

Hydrogenation of a lithium-potassium (double-cation) amide (LiK(NH₂)₂), which is generated as a product by ammonolysis of litium hydride and potassium hydride (LiH-KH) composite, is investigated in details. As a result, lithium amide (LiNH₂) and KH are generated after hydrogenation at
