AlOOH로부터 AlN분말의 합성
Synthesis of AlN Powders from AlOOH
E-mail:
In this study, we report a method to synthesize the aluminum nitride (AlN) powders from aluminum oxyhydroxide (AlOOH). AlOOH powders were prepared from the aluminum hydroxide () by heattreatment at the reaction temperature of . Simple heat treatment of AlOOH in the flow of gas leads to the formation of hexagonal AlN powders through intermediate conversion of and . The FTIR transmission spectra show a broad peak related to Al-N bonds centered around 690 confirming the presence of AlN. The major peaks in Raman spectra were observed in 250 and 659 . From the results, synthesized powders from the AlOOH powders were confirmed AlN powders.
