Microstructural Modifications Induced by Hydrogen Absorption in Mg5Ga2 and Mg6Pd
We have recently proposed a new method to design one-dimensional structures of MgH2 in the nano- and micrometers ranges by hydrogen induce disproportionation of bulk Mg24Y5. The present study confirms the same behavior in hydrogenated Mg5Ga2 and Mg6Pd. Single-crystalline one-dimensional structures and micro-particles of MgH2 are formed by hydrogen absorption and subsequent partial disproportionation of Mg5Ga2 and Mg6Pd. The MgH2 whiskers and particles grow in different morphologies for different alloying partners. Growth mechanisms are proposed in relation to the morphology and the chemical surface composition of original compounds.
