The dependence of chemical reaction between Mg (NH 2) 2 and MgH 2 on the ball-milling conditions has been investigated. While the decomposition of the component Mg (NH 2) 2 resulted in gaseous products consisting mainly of ammonia, the mixtures of Mg (NH 2) 2 -MgH 2 prepared by ball-milling released H 2 at temperatures as low as 65 °C.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134-141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
