چکیده انگلیسی
The CaLi2 alloy which was prepared by the induction melting method has been successfully hydrogenated. The CaLi2 alloy synthesized had a hexagonal C14-type Laves phase structure and absorbed 6.8–7.1 mass% hydrogen under the temperature range from 273 K to 393 K. The hydrogenated CaLi2 which consisted of CaH2 and LiH hydride phases did not desorb hydrogen under 10 kPa-H2 at the same temperatures. The hydrogen absorption kinetics measured under 3.1 MPa-H2 at room temperature showed that the hydrogen content reached to 6 mass% in 10 s. No obvious hydrogen desorption from the hydrogenated CaLi2 was observed even after evacuation for 20 h at 623 K.
