Wöhler process

Wöhler process was used in the production of aluminium. It involved the reduction of anhydrous aluminium chloride with potassium, and produced powdered aluminium.

In 1827, Friedrich Wöhler refined a process discovered by Hans Christian Oersted, a Danish chemist, who first produced impure aluminium in 1825. This allowed him to establish the specific gravity of aluminium in 1845.
