Aluminium oxide - Wikipedia

Aluminium oxide is an amphoteric substance, meaning it can react with both acids and bases, such as hydrofluoric acid and sodium hydroxide, acting as an acid with a base and a base with an acid, neutralising the other and producing a salt.

Right to Know Hazardous Substance Fact Sheet

Aluminum Oxide is a white, odorless, crystalline (sand-like) powder. It is used in abrasive and refractory materials, ceramics, laboratory-ware and paper, and as an adsorbent for gases. Hazard Rating Key: 0=minimal; 1=slight; 2=moderate; 3=serious; Reasons for Citation Aluminum Oxide is on the Right to Know Hazardous Substance List because it is cited by OSHA, ACGIH, NIOSH,

Aluminum oxide | Al2O3 - PubChem

ALUMINUM OXIDE is chemically amphoteric (behaves as a weak acid in the presence of base and as a weak base in the presence of acid). May act catalytically. May cause the exothermic polymerization of ethylene oxide. May cause the vigorous polymerization of vinyl chloride [MCA SD-75, 1970]. The degree of subdivision of the aluminum oxide may affect the vigor of such reactions.

Rust does not adhere to iron, but flakes off, exposing a fresh iron surface to be corroded further. But aluminum oxide forms a tightly-adhering layer on the surface of aluminum, and protects the metal underneath from further corrosion. This is a good thing, because aluminum is a much more reactive metal than iron! Exercise 20.
