Aluminium and Titanium
These are two metals with a low density
which means they are lightweight for
their size.
Aluminium is used for
aircraft, trains,
overhead power
cables, saucepans
and cooking foil.…read more

The metal burns in air and is the only element
that burns in nitrogen. It is marvellous in
fireworks.…read more

Aluminium and Titanium resist
corrosion as they have a very thin layer
of their oxides on the surface, which stops
air and water getting to the metal.…read more

Unlike iron, aluminium and titanium
cannot be extracted from their oxides by
reduction with carbon because:
Aluminium is more reactive than
carbon, so the reaction does not work.
Titanium forms titanium carbide with
carbon, which makes the metal brittle.…read more

Aluminium is mined in
huge scales as bauxite.
· In order to isolate pure aluminium,
impurities must be removed from the
· This is done by the Bayer process,
which involves treatment with sodium
hydroxide solution, followed by
purification using electrolysis.…read more

Titanium is isolated
using the
Kroll method.
This involves the action of chlorine and
carbon on the titanium ore followed by
fractional distillation and then
reduction with magnesium.…read more
