Abstract

CaLi2-xMgx (0 ≤ x ≤ 2) which has the C14-type Laves phase structure has been successfully synthesized and hydrogenated. The C14-type Laves phase structure was kept after hydrogenation of CaLi2-xMgx (x = 0.2, 0.5, 1). After hydrogenation of CaLi2 and CaMg2, the Laves phase disappeared. The CaH2 and LiH phases were formed from CaLi2 and the CaH2 and Mg phases from CaMg2, respectively. CaLi2-xMgx (0 < x < 2) ternary alloys formed stable hydride phases with the C14-type Laves phase structure in contrast to CaLi2 and CaMg2 binary alloys.
