Results were presented of the reaction of intermetallic compounds (IMC) and alloys of the systems Y-Mg, La-Mg, and Ce-Mg with hydrogen. Alloys were obtained by fusing the metals under a layer of LiCl-KCl flux in a resistance analysis. Thermal analysis showed that the hydrides undergo decomposition where at 470-580 K the hydrides decompose into binary hydrides of REE and magnesium. CeMg/sub 3/H/sub 3/ decomposed in two stages with the formation of the IMC CeMg/sub 12/ in the intermediate stage. The temperature of hydrogen evolution from the La and Ce hydrides agreed, within the determination accuracy limits, with individual LaH/sub 2/ and CeH/sub 2/, indicating that they do not react markedly with liquid magnesium.
