Isothermal hydrogen release and uptake reactions studied for a sample of magnesium hydride ball-milled with scandium chloride (5.0 mol%). The SR-PXD data were collected using the sapphire-based cell (A) at a fixed temperature of 593 K for a period of 30 min and the hydrogen pressure varied in the range ∼10−3 to 100 bar. The X-ray exposure time was 5 s, the time resolution was 9.95 s per powder pattern and the selected X-ray wavelength was λ = 0.94608 Å. |
