Abstract

Formation region and hydrogen desorption and absorption properties of the perovskite-type structure in Li_xNa_1-xMgH₃ with x = 0, 0.17, 0.33, 0.50 and 1.00 were studied in the present work. The experimental results are reasonably explained from the viewpoint of the geometric restrictions of ions that are described by so-called Goldschmidt tolerance factors. In NaMgH₃ (x = 0), two plateau pressures of about 0.040 and 0.15 MPa were clearly detected by hydrogen pressure-composition (p-c) isotherm measurement at 673 K. Moreover, NaMgH₃ can be reversibly formed in 1.0 MPa of hydrogen at 673 K, from the decomposed phase of elemental Na and Mg.
