Synthesis and Characterization of Alumina Nanoparticles: A Case Study
https://orcid.org/0000-0002-7805-3335
Abstract Alumina nanoparticles ($ Al_{2} $$ O_{3} $ NPs) were successfully prepared from aluminum nitrate precursor and methanol using the precipitation method, while NaOH was added after stirring. The prepared $ Al_{2} $$ O_{3} $ NPs were synthesized at the calcination temperature of 400 °C and 600 °C for 2 h. Later, the synthesized $ Al_{2} $$ O_{3} $ NPs were characterized by X-ray diffraction and scanning electron microscopy analysis. The conducted experiments show that the calcination temperature was found to have a strong influence on the $ Al_{2} $$ O_{3} $ NPs’ stability and processing time. It was clearly observed that with the increase in calcination temperature the crystallite size of the sample increases, indicating the enhanced crystallinity. The crystallite size of the synthesized $ Al_{2} $$ O_{3} $ NPs was in the range of 53–72 nm. The economic analysis of the produced $ Al_{2} $$ O_{3} $ NPs has indicated that the precipitation method is cost-effective.
