摘要：

The effect of the parameters of mechanochemical activation of magnesium hydride and MgH2-graphite binary compositions on the parameters of materials and their hydrolytic activity has been studied. It is concluded that mechanochemical treatment increases the reactivity of magnesium hydride in its reaction with water. Graphite provides an additional activating effect during the mechanochemical treatment of MgH2. A deformation dose of 20 kJ/g was determined to be the optimum one for achieving the highest reactivity in the hydrolysis reaction with the formation of MgH2-graphite composites. As a result of the hydrolysis of such materials, up to 970-1280 mL hydrogen per composite gram is evolved in 40 min of the reaction with water without an additional change in the solution acidity.
