A brownish white solid product precipitated rapidly by simply mixing anhydrous aluminum chloride into ethylenediamine at room temperature in flowing dry N_2. Any crystallized compounds were not formed from the resulting organic precursor after calcination at 800℃ for 5 h in flowing dry N_2,but formation of amorphous AlN was suggested from the FT-IR spectroscopic analysis. Crystallized AlN powder could be synthesized from the precursor after calcination at 1200℃ for 5 h in flowing dry N_2. The crystallite size of AlN powder was less than 25 nm, but the particle size was in the range of 60-100 μm due to agglomeration of fine particles under the present synthesis conditions., 長崎大学工学部研究報告 Vol.32(59) p.185-190, 2002}, pages = {185--190}, title = {Formation Mechanism of Aluminum Nitride Powder via Organic Precursor Prepared from Anhydrous Aluminum Chloride and Ethylenediamine}, volume = {32}, year = {2002} }
