Abstract
A new hexagonal intermetallic phase has been detected in a LaMg2Cu2 prepara tion, which absorbs large quantities of hydrogen (similar to 2.4 wt.%). The dissociation pressure of the hydride reaches nearly similar to 0.4 atmosph ere at 170 degrees C. The hydrogen absorption/desorption properties have be en determined by thermal analysis and pressure-composition isotherms. (C) 1 999 Elsevier Science S.A. All rights reserved.
