Aluminum and Oxygen gas react to form Aluminum Oxide.
Main application markets for aluminium oxide nanoparticles are in:
"Typically, the synthesis of oxide nanoparticles involves the slow reaction of a weak oxidizing agent, such as hydrogen peroxide, with dilute solutions of metal salts or complexes in both aqueous and non-aqueous solvent systems," said Dr. Thomas Sutto, NRL research chemist. "The rapid exothermic reaction of potassium superoxide with the salt solutions results in the formation of insoluble oxide or hydroxide nanoparticulates."

Scientists at the U.S. Naval Research Laboratory (NRL) Materials Science and Technology Division have developed a novel one-step process using, for the first time in these types of syntheses, potassium superoxide (KO2) to rapidly form oxide nanoparticles from simple salt solutions in water.

Aluminium oxide nanoparticles/Nano-Alumina (Al2O3-NPs) exhibit low electric conductivity, resistance to chemical attack, high strength, extreme hardness, and high melting point.

Recent applications include oil and gas aluminium drill pipelines. Application of aluminium oxide nanofluids in enhanced oil recovery (EOR) has also been increasing in the recent years. The ability of nanoparticles to alter certain factors in the formation and in oil properties can enhance recovery.
