Aluminium has a high chemical affinity to oxygen, which renders it
suitable for use as a reducing agent in the thermite reaction. A
fine powder of aluminium metal reacts explosively on contact with
liquid oxygen; under normal conditions, however, aluminium forms a
thin oxide layer (~5 nm at room temperature) that protects the
metal from further corrosion by oxygen, water, or dilute acid, a
process termed passivation. Because of its general resistance to
corrosion, aluminium is one of the few metals that retains silvery
reflectance in finely powdered form, making it an important
component of silver-colored paints. Aluminium is not attacked by
oxidizing acids because of its passivation. This allows aluminium
to be used to store reagents such as nitric acid, concentrated
sulfuric acid, and some organic acids.
