[27], In 1824, Danish physicist Hans Christian Ørsted attempted to produce the metal. "While aluminum was discovered by Hans Christian Oersted, Denmark, 1825 (impure form); most credit Wohler with isolating it in1827. The factory in Salindres did not wish to improve their process. [109] Aluminium freight cars first appeared in 1931. The Hall-Héroult and Bayer processes are still used today to produce nearly all of the world's aluminum. [48] Production in 1890 alone was 175 metric tons. Hall was able to prove his originality thanks to his keeping record on experiments. Electrolysis of pure alumina is impractical given its very high melting point; both Héroult and Hall realized it could be lowered significantly by the presence of molten cryolite. [78], The first large-scale production method was independently developed by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886; it is now known as the Hall–Héroult process. At the start of the Renaissance, the nature of alum remained unknown. [73][i] In 1889, Hall's production began to use the principle of internal heating. [102] The peak in production was followed by a decline, then a swift growth. For instance, aluminium bronze is applied to make flexible bands, sheets, and wire, and is widely employed in the shipbuilding and aviation industries. [66] In 1884, American architect William Frishmuth combined production of sodium, alumina, and aluminium into a single technological process; this contrasted with the previous need to collect sodium, which combusts in water and sometimes air;[67] his aluminium production cost was about $16 per pound (compare to silver's cost of $19 per pound, or the French price, an equivalent of $12 per pound). [51] The metal was presented as "the silver from clay" (aluminium is very similar to silver visually), and this name was soon widely used. [94][95], The total amount of unalloyed aluminium produced using Deville's chemical method from 1856 to 1889 equals 200 metric tons. [67] Netto's main advantage, the high purity of the resulting aluminium, was outmatched by electrolytic aluminium and his company closed the following year. [104] Aluminium was used heavily in aircraft production and was a strategic material of extreme importance; so much so that when Alcoa (successor of Hall's Pittsburgh Reduction Company and the aluminium production monopolist in the United States at the time) did not expand its production, the United States Secretary of the Interior proclaimed in 1941, "If America loses the war, it can thank the Aluminum Corporation of America". This name was given by Humphry Davy, an English chemist, who, in 1808, discovered that aluminium could be produced by electrolytic reduction from alumina (aluminium oxide), but did not manage to prove the theory in practice. [90] By 1890, Hall's company still lacked capital and did not pay dividends; Hall had to sell some of his shares to attract investments. I don't think it was particularly discovered. [128] The aluminium industry began promoting the recycling of aluminium cans in an attempt to avoid restrictions on them. Flexible glass? Recycling grew overall but depended largely on the output of primary production: for instance, as electric energy prices declined in the United States in the late 1930s, more primary aluminium could be produced using the energy-expensive Hall–Héroult process. on Who discovered Aluminium? [98] The aluminium can was first manufactured in 1956 and employed as a container for drinks in 1958. Scientists suspected than an unknown metal existed in alum as early as 1787, but they did not have a way to extract it. Aluminium began to be used in engineering and construction. Aluminium alloys found many uses in the late 19th and early 20th centuries. At one point (1855), aluminum was worth $100,000 a pound! Alum is potassium aluminum sulfate. It is highly reactive and easily combines with most other elements. Alum is a compound of potassium, aluminum, sulfur, and oxygen. Today, I bring you the victory over the Turk. [104] Aluminium is produced in greater quantities than all other non-ferrous metals combined. [73], Modern production of the aluminium metal is based around the Bayer and Hall–Héroult processes. Further, Pierre Berthier discovered aluminium in bauxite ore and successfully extracted it.Frenchman Henri Etienne Sainte-Claire Deville improved Wöhler's method in 1846, and described his improvements in a book in 1859. [70] In 1886, American engineer Hamilton Castner devised a method of cheaper production of sodium, which decreased the cost of aluminium production to $8 per pound, but he did not have enough capital to construct a large factory like Deville's. If you will give orders to engage workmen, build furnaces, and smelt the ore, you will provide all Europe with alum and the Turk will lose all his profits. [100] Aviation used a new aluminium alloy, duralumin, invented in 1903. Aluminium coins continued to be used but while they symbolized a decline on their introduction, by 1939, they had come to represent power. The introduction of these methods for the mass production of aluminium led to extensive use of the light, corrosion-resistant metal in industry and everyday life. [13] In 1760, French chemist Théodore Baron d'Hénouville [fr] expressed his confidence that alumina was a metallic earth. They convinced Héroult to return to France, purchased his patents, and appointed him as the director of a smelter in Isère, which produced aluminium bronze on a large scale at first and pure aluminium in a few months. Existing works by Chinese alchemists show that alloys with a small aluminium content could be produced in China. The English chemist Sir Humphrey Davy underlined the existence of the element arguing that "alum" was the salt of an unknown metal which he said should be called ‘alumium’. [49] Deville was able to produce an ingot of the metal. It was only reduced after the initiation of the first industrial production by French chemist Henri Étienne Sainte-Claire Deville in 1856. When asking professionals for advice, he was told there was no demand for aluminium but some for aluminium bronze. It took the scientists who discovered aluminum years of experimentation before they succeeded in refining this elusive element. [14] German pharmaceutical chemist Carl Wilhelm Scheele demonstrated that both alum and silica originated from clay and alum did not contain silicon in 1776. [27], In 1807, British chemist Humphry Davy successfully electrolyzed alumina with alkaline batteries, but the resulting alloy contained potassium and sodium, and Davy had no means to separate the desired metal from these. [54] At the next fair in Paris in 1867, visitors were presented with aluminium wire and foil as well a new alloy—aluminium bronze, notable for its low cost of production, high resistance to corrosion, and desirable mechanical properties. The Chinese did not have the technology to produce pure aluminium and the temperatures needed (around 2000 °C) were unachievable. German chemist Friedrich Wohler recreated Oersted’s experiment and came to the conclusion that the resulting metal was in fact pure potassium. World production continued to rise, reaching 58,500,000 metric tons in 2015. On April 2, 1889, Charles Martin Hall patented an inexpensive method for the production of aluminum, which brought the metal into wide commercial use. [64], Other production sites began to appear in the 1880s. Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. In 1846, French chemist Henri Etienne Sainte-Clair Deville made modifications on the Wohler system, such as replacing the significantly more costly potassium with the comparatively cheaper sodium. [19] German chemist Johann Heinrich Pott showed the precipitate obtained from pouring an alkali into a solution of alum was different from lime and chalk in 1746. While not quite the man who discovered aluminum, British chemist and inventor Sir Humphry Davy, can be credited for naming it (first as “alumium” before being given its current designation) in 1808. [2] The ancients used it as a dyeing mordant, in medicine, in chemical milling, and as a fire-resistant coating for wood to protect fortresses from enemy arson. Deville quickly realized electrolytic production was impractical at the time and moved on to chemical methods, presenting results later that year.
