The Thermite Reaction
- What is it?
- This highly
exothermic
reaction
occurs
between
iron (III)
and
aluminium.
- This
produces
molten iron.
- This
produces
molten iron.
- This highly
exothermic
reaction
occurs
between
iron (III)
and
aluminium.
- Why does it happen?
- The reaction occurs
because aluminium is a
more reactive metal
than iron.
- Aluminium
steals the
oxygen from iron
oxide leaving
iron and
aluminium oxide.
- Aluminium
steals the
oxygen from iron
oxide leaving
iron and
aluminium oxide.
- This is a
competition
reaction.
- The reaction occurs
because aluminium is a
more reactive metal
than iron.
- How does it happen?
- The heat from the
magnesium ribbon
(once lighted) starts
the reaction, and
once underway, it can
reach temperatures of
up to 2000°C.

- Any Similar Reactions?
- To vary the
reaction, you
could use a
number of metal
oxides. The
important thing
to remember is
that the metal
must be more
reactive than
the metal oxide.

- Who reacts?
- iron (III) oxide + aluminium → aluminium oxide + iron
- iron (III) oxide + aluminium → aluminium oxide + iron
