Notes on the application of metal hydrides

4 Notes on the application of metal hydrides. The study of the hydride formation in metallic systems is important not only in view of the (often deleterious) 

Structure type Examples of isostructural phases Composition ranges at.% H 

Quantitative predictions about the heats of formation of hydrides of intermetallic compounds have been discussed by Shilov etal. (1989) they studied reversible and irreversible transformations in intermetallic compound-hydrogen systems and observed that four basic types of PIT diagrams exist for these systems.

Lithium (Li, [Hep.v1), name and symbol from the Greek lithos (stone). Discovered (1817) by J. August Arfvedson, isolated (1818) by Sir H. Davy (1821) and by William T. Brande.
