| Abstract |
Among many metals magnesium has excellent hydrogen-storage characteristics except that its hydriding and dehydriding rates are low. Many works have been carried out in oredr to ameliorate the reaction rates of magnesium with hydrogen. However, their processes of the sample preparation were energy -consuming and complicated. In this work, to simplify the process of sample preparation, samples with a composition 2Mg + Fe were prepared only by mixing Mg and Fe. For these mixtures the following hydrogen-storage characteristics were investigated : formation of dimagnesium iron hydride, activation process for hydriding - dehydriding reaction, equilibrium plateau pressures, microstructure of the hydrided sample, life as a hydrogen - storage material, and hydriding and dehydriding rates. |
