Abstract
The experimental data on the mechanism of hydride dispersion of intermetallic compounds of the LaNi5 type and the crystal structures of hydride phases based on these compounds were analyzed. A new approach was suggested and substantiated, which allows one to consider hydride dispersion as a result of a redox process associated with the formation of Hδ− hydride ions at concentrations of hydrogen in the solid hydrideC H>-C H cr. The value ofC H cr is determined by the redox potential of the reaction Hδ++Mδ−⇌Hδ′−+Mδ′+.
