Aluminium oxide is chemical compound of aluminum and oxygen with chemical formula Al2O3, its most common of several aluminium oxides. Aluminium oxide occurs naturally in it's crystalline alpha phase as mineral corundum.
Aluminium oxide is very hard solid (9 Mohs scale). It's electrical insulator.
Aluminium oxide is often present in sandpapers, you can also buy it from mineral collectors as corrundum or gemstones like ruby or saphire.
Aluminium oxide is a product of thermite reaction: M2O3 + 2Al → Al2O3 + 2M
No special handling is necessary.
Avoid inhalating the dust. Aluminium oxide isn't flamable or explosive.
Storage in closed bottles is adequate.
Aluminium oxide could be safely dumped with normal trash or spilled out in a soil.
