In addition, new peaks corresponding to Li5FeO4 and Fe0.974O were observed for the doped sample as presented in Figure 7. This result demonstrated that the reaction between LiAlH4 and Fe2O3 occurred during ball milling by forming ternary Li-Fe oxide and Fe oxide species with a reduced valance state.

causes a displacement reaction between various metals and metal oxides. Sometimes ball milling causes a self-propagating heat synthesis reaction (SHS) to occur. This study was undertaken to see whether the ball milling technique could provide a method to extract pure silicon from silicon oxide. Since silicon oxide and aluminum are

In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers into a colloidal solution that acts as the precursor for an integrated network (or gel) of either discrete particles or network ...

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.
