History of Aluminum
The story of aluminum is, in many ways, a story of human innovation and the persistent pursuit of knowledge. The history of aluminum dates back to around 5000 BC when people used alum, a naturally occurring compound comprised mainly of aluminum, as a dyeing mordant and for medicinal purposes. However, it wasn’t until the 19th century that aluminum was identified as an element and eventually isolated.
In 1807, Sir Humphry Davy, an English chemist, first proposed the existence of an unknown metal he named ‘alumium’, which was later renamed to aluminum. Despite his efforts, Davy was unable to isolate aluminum due to its strong affinity for oxygen. It wasn’t until 1825 that Hans Christian Oersted, a Danish physicist, managed to produce a small amount of pure aluminum by reducing anhydrous aluminium chloride with potassium amalgam.
Despite this breakthrough in understanding what does aluminum look like in its pure form, the process was far too expensive for commercial production. In fact, due to the difficulty in isolating it, aluminum was considered more valuable than gold or silver during the mid-19th century. Napoleon III supposedly reserved a set of cutlery made from aluminum for special guests while others ate with gold utensils.
The high cost and scarcity of aluminum remained until an American chemist named Charles Martin Hall and a Frenchman named Paul Héroult independently developed the same method of extracting aluminum in 1886. This method, now known as the Hall-Héroult process, involves dissolving alumina (aluminum oxide) in molten cryolite and then passing a powerful electric current through it. This causes the oxygen atoms to be removed from the alumina and leaves behind pure aluminum.
The discovery of this economical method marked a turning point in the history of aluminum. Suddenly, what was once a precious metal became readily available and cheap to produce. This ignited a boom in the use of aluminum across multiple industries, from aviation to architecture, that continues to this day.
Today, aluminum is the most abundant metal in the earth’s crust and the third most abundant element after oxygen and silicon. Its lightweight nature combined with its resistance to corrosion makes it a vital component in various applications.
