Y_3Al_2的氢化物相为Y_3Al_2 H_(6.5)和Y_3Al_2 H_(2.2)。在373 K和3.0MPa的氢气气氛下,Y3 Al 2发生了氢还原反应,生成Y3Al2H6.5;在0.1MPa的氦气气氛下,Y3Al2H6.5在873 K发生了氢还原反应,生成Y3Al2H2.2。在Y-Al体系中首次证实了Y_3Al_2H_6.5和Y_3Al_2H_2.2之间的部分可逆还原/脱氢反应。
Hydride phases of Y3Al2, namely Y3Al2H6.5and Y3Al2H2.2, were newly formed. Y3Al2was hydrided to Y3Al2H6.5at 373K and 3.0MPa of hydrogen, and Y3Al2H6.5was dehydrided to Y3Al2H2.2up to 873K at 0.1MPa of helium. Furthermore, partial reversible hydriding/dehydriding reactions between Y3Al2H6.5and Y3Al2H2.2were confirmed for the first time in the Y–Al system.
