Sehlooho sena se bua ka thepa le lits'ebetso tsa alumina nanoparticles. Aluminium ke sehlopha sa P sa 3rd period element, ha oksijene e le P sehlopha sa 2nd period element.
Sebopeho sa alumina nanoparticles ke spherical and white powder.Alumina nanoparticles (liforomo tsa metsi le tse tiileng) li khetholloa e le tse ka tukang haholo le tse halefisang, tse bakang mahlo a matla le ho hema ho hema.
Alumina nanoparticlese ka etsoa ka mekhoa e mengata, ho kenyelletsa le ho sila ka bolo, sol-gel, pyrolysis, sputtering, hydrothermal, le laser ablation.Laser ablation ke mokhoa o tloaelehileng oa ho hlahisa li-nanoparticles hobane o ka etsoa ka khase, vacuum kapa mokelikeli. ho bonolo ho bokella ho feta nanoparticles libakeng tse nang le khase.Haufinyane tjena, litsebi tsa k'hemistri Max-Planck-Institut für Kohlenforschung e Mülheim an der Ruhr li fumane mokhoa oa ho hlahisa corundum, e tsejoang hape e le alpha-alumina, ka mokhoa oa li-nanoparticles tse sebelisang mokhoa o bonolo oa mechine, e fapaneng haholo.
