## Abstract One‐dimensional nanorods of cubic aluminum oxide (γ‐Al~2~O~3~) have been synthesized by DC electric arc discharge of Fe and Al powders. It is seen that the diameters of the γ‐Al~2~O~3~ nanorods are relatively uniform, ranging from 20 to 30 nm. On the basis of detailed transmission elect
Nanosized alumina powder was prepared from a mixture of aluminium nitrate and carbon black through microwave heating (2.45 GHz and 900 W) for different times. The products were characterized by powder Xray diffraction. The results showed that γ-Al 2 O 3 was the main phase for powder samples heated f
