Mechanical Milling of Lithium with Metal Oxide and its Reactivity with Gases

Article Preview

Lithium is one of the active metals and reacts with nitrogen even at room temperature. In this study, in order to grind and activate Li, the mechanical milling of Li with stable metal oxide, namely, Al2O3 and MgO, using a high energy vibrating ball mill was performed. In the case of Li- MgO system, it reacts with N2, but hardly reacts with O2. The reaction with N2 generally produces Li3N, while for some vigorous reactions the Mg3N2 and Li2O are produced as the major phases. In the case of Li-Al2O3 system, however, reactivities with both N2 and O2 are high. The difference will be explained in terms of the reaction mechanism and the Li state.
