In this communication, the results of synthesis,characterization and dehydr
iding behaviour of the intermetallic compound La2-xCaxMg17 are presented. P
ressure-composition hydrogen desorption isotherms are measured at high temp
erature. The influence of Ca substitution on the hydriding-dehydriding char
acteristics of the intermetallic phase La2Mg17 has been investigated. (C) 1
