Synthesis and characterization of Magnesium-Iron-Cobalt complex hydrides.

ABSTRACT: The formation, structure and deuterium desorption properties of Mg₂Fe_xCo_(1-x)D_y (0 ≤ x ≤ 1 and 5 ≤ y ≤ 6) complex hydrides were investigated. The synthesis was carried out by reactive ball milling, using a mixture of powders of the parent elements in D₂ atmosphere. The formation of quaternary deuterides was identified from Rietveld refinements of powder X-Ray diffraction and powder neutron diffraction patterns, and from infrared attenuated total reflectance analysis. It was observed that the crystal structure of deuterides depends on the transition metal fraction. For Co-rich compositions, i.e. up to x = 0.1, hydrides have the tetragonal distorted CaF₂-type structure (space group P4/nmm) of Mg₂CoD₅ at r
