Full Description of Aluminium Oxide Nanoparticles
Aluminium Oxide Nanoparticles often called Aluminium Oxide Nanopowder and abbreviated as Al2O3 Nanoparticles, are spherical nanosized particles of alumina. Aluminium is available abundantly on earth. It has wide applications in different consumer products and applications due to its novel characteristics. Al2O3 nanoparticles have a rod-like shape with a width around 10 nm and a length between 20–50 nm. Aluminium oxide consists of two aluminium atoms and three oxygen atoms. They are bonded collectively in a hexagonal close-packed (HCP) crystal structure. The general name of the compound is alumina or corundum, which are also the core mineral found in rubies and sapphires. It isn’t very pleasant and homogeneously oxidized. The derivation of Aluminium oxide is done from the ore of Aluminium – the bauxite mineral. Bauxite is a sedimentary rock with Aluminium compounds in a mixture with other minerals and non-metals. It also has oxides such as hematite (Fe2O3), quartz (SiO2), and magnetite (Fe3O4). After obtaining bauxite, it is crushed and purified into Aluminium by the Bayer process. Alumina is achieved before the final Aluminium production. This takes place just after the bauxite is coated with a hot sodium hydroxide solution to obtain Aluminium hydroxide. It is then calcinated into alumina. Alumina nanoparticles develop from the alumina or corundum. The preferred method of nanoparticle production is laser ablation. It has versatility in terms of the size of the produced nanoparticles. As the laser beam is pure, it is easy to obtain the purest nanoparticles differently.
The laser beam interacts with the solid it focuses on, forms plasma, and evaporates types of particles. The expanded channel then encounters the ambient gas or fluid that interacts with the beam to form alumina nanoparticles in the configuration.
