Aluminum Oxyhydroxide Nanopowder (Al2O3)

Aluminum oxide (or aluminum(III) oxide) is a chemical compound of aluminum and oxygen with the chemical formula Al₂O₃. It occurs naturally in its crystalline phase as the mineral corundum, varieties of which form the gemstones ruby ​​and sapphire. Al₂O₃ is used to produce aluminum metal, as an abrasive due to its hardness, and as a refractory material due to its high melting point. Al₂O₃ is an electrical insulator but has a relatively high thermal conductivity for a ceramic material. It is used as an abrasive in sandpaper, grinding wheels, and polishing compounds. Its hardness and durability make it practical for material removal and surface finishing. Aluminum oxide is also insoluble in water.

Properties:

• High hardness: Alumina nanopowder has high hardness, which makes it suitable for abrasive applications.
