Recent Progress on the Production of Aluminum Oxide (Al2O3) Nanoparticles: A Review

This study aims at discussing several methods to produce aluminum oxide (Al2O3) synthesis along with the advantages and disadvantages of each method used. In general, are available: (1) precipitation, (2) combustion, (3) sol-gel, (4) wet chemical, (5) in supercritical water conditions, (6) microwave, (7) mechanochemical, (8) hydrolysis, most efficient for synthesizing Al2O3 is precipitation because it facile simplest (compared other methods), can be proceeded using inexpensive raw materials, produces less pollution, has advantages: high purity product, thermal stability, nearly homogeneous nanoparticle size, control desired particle size. The results help provide comparisons producing various methods.
