Abstract

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 3N. First, we studied the relationship between Al/Li 3N 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 3N<4/1. Next, we performed AlN synthesis on an AlN/SiC template under an Al-rich condition. The results suggested that a large AlN singlephase 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.
