Effect of the Partial Replacement of CaH2 with CaF2 in the Mixed System CaH2 + MgB2
(2014) In Journal of Physical Chemistry C 118(49). p.28409-28417- Abstract
- In this work the effect of a partial replacement of CaH2 with CaF2 on the sorption properties of the system CaH2 + MgB2 has been studied. The first five hydrogen absorption and four desorption reactions of the CaH2 + MgB2 and 3CaH(2) + CaF2 + 4MgB(2) systems were investigated by means of volumetric measurements, high-pressure differential scanning calorimetric technique (HP-DSC), B-11 and 19F MAS NMR spectroscopy, and in situ synchrotron radiation powder X-ray diffraction (SR-PXD). It was observed that already during the mixing of the reactants formation of a nonstoichiometric CaF2-xHx solid solution takes place. Formation of the CaF2-xHx solid solution sensibly affects the overall hydrogen sorption reactions of the system CaH2 + MgB2.
