The first and outermost layer is the surface layer. It is known that nanoparticles are not point objects and have three distinctive layers to them. The arrangements of the atoms in the nanoparticles are different whenever the size is changed because of the structures that characterize the nanoparticles. The physiochemical properties of the nanoparticles are influenced heavily by their size and dimensions. The decrease in size has various advantages but the important factor is the change in the chemistry of the nanoparticles compared to their larger counterparts that fascinates the incorporation of these nanoparticles into many fields of science and engineering. Branching into the field of nanoparticles paints a new picture for the possible applications of the already useful and abundant compound of aluminum oxide. Thus, the applications of its use can't efficiently be further expanded to other areas like catalysis or adsorption. Bulk aluminum’s large diameter doesn’t allow it to have a larger surface of interaction with its surroundings. ![]() The properties of bulk alumina that allow it to be such a versatile element in the industry are different from those of its nanoparticles. Aluminum nanoparticles are usually found in two states, nearly spherical shaped individual particles or as oriented fibers. It is also easier to set specifications for the kind of nanoparticles you desire to obtain. This is very advantageous since the collection of nanoparticles in a gaseous environment is harder and cumbersome than in a liquid. Laser ablation is convenient since it can be performed in the gas, liquid or even a vacuum environment. Alumina nanoparticles can be obtained by several methods including, pyrolysis, sputtering, sol gel and the most commonly preferred technique laser ablation. These are nanosized spherical particles from an alumina bulk. ![]() What are Aluminum oxide (Al2O3) nanoparticles? The common name for the compound is alumina and it has found several applications in the industry due to its abundance and abrasiveness. Aluminum oxide is a compound composed of two aluminum atoms and three oxygens bonded together in a hexagonal close packed (hcp) crystal structure. ![]()
