Structure of Partly Vacuum Extracted MgH₂ Samples

Abstract:

The structure of partly desorbed and quenched samples of MgH₂ has been investigated by the neutron diffraction method. In ambient conditions a partly desorbed sample demonstrates high stability, while the same sample quenched at low temperature decomposed into Mg after several days. Obtained neutron data showed that all studied samples contain coexisting Mg and MgH₂ phases. Hydrogen distribution for both quenched and non-quenched samples is similar. Hydrogen atoms occupied sites predominantly in the MgH₂ lattice, whereas Mg lattice is free of the hydrogen.
