A new route for synthesizing gallium nitride (GaN) from gallium oxide (Ga 2 O 3) and lithium nitride (Li 3 N) by milling is proposed in this paper. The milling was performed in a planetary ball mill with unisize ZrO 2 balls to induce mechanochemical reaction between the starting materials in order to prepare GaN powder. The formation of GaN was confirmed in XRD patterns, and the peak ...
