    Sep 18, 2009 · A non-thermal process for reducing indium (III) oxide (In 2 O 3) and/or indium tin oxide (ITO) into indium–metal by milling with lithium nitride (Li 3 N) under (NH 3) or nitrogen (N 2) gas environment is proposed in this paper. Milling operation causes mechanochemical reaction in the systems of In 2 O 3 /ITO and Li 3 N, to form In and LiOH.
