Abstract

This study centered on the synthesis and characterization of Al2O3 nanoparticles, vital for assessing material properties prior to their application in Science, Engineering, and Technology. Aluminum nanoparticles were synthesized utilizing aluminum nitrate nonahydrate and ethanol as precursors. The resulting nanoparticles underwent calcination at 1000°C for 1 h and were subsequently characterized via X-ray Diffraction (XRD). The outcomes revealed the presence of corundum (α–Al2O3) as a phase within the Al2O3 nanoparticles. The average crystallite size was determined to be 30.12 nm, accompanied by an interplanar spacing of 0.2187 nm. Dislocation analysis yielded a value of 0.000515 lines/nm², while micro-strain was calculated at 0.003701 nm-2.
