Fig. 5.
XRD patterns of the Mg particles treated in water (a) in the presence/absence of ultrasonic impact, b) in ethanol or ethylene glycol, respectively. The symbol “o” corresponds to the brucite phase, the arrows are attributed to the magnification of the regions of the magnesium hydride reflexes which were detected in the samples after sonication. The duration of treatment comprised 15 min. Thermal analysis of the sample ultrasonically treated in Mg aqueous suspension during 15 min (c – TG curve, d – DTG curve, e – DSC curve, the arrow shows the direction of the exothermic processes). The symbol X corresponds to the designation of the main peaks of Mg(OH)2 and MgH2 decomposition.
