We investigated the possibility of AlN synthesis using Li‐Al‐N solvent. In this work, Li‐Al‐N solvent was obtained by heating a mixture composed of Al and Li 3 N. First, we studied the relationship between Al/Li 3 N composition of the initial mixture and shape of obtained crystal. The results showed that polyhedral crystals instead of needle‐like crystals were obtained under an Al‐rich condition, i.e., 4/3 < Al/Li 3 N < 4/1. Next, we performed AlN synthesis on an AlN/SiC template under an Al‐rich condition. The results suggested that a large AlN single‐phase region was formed by using the template. The possibility of growth of bulk AlN using Li‐Al‐N solvent was shown by the present investigations.
