Charles Martin Hall (December 6, 1863 – December 27, 1914) was an American inventor, businessman, and chemist. He is best known for his invention in 1886 of an inexpensive method for producing aluminum , which became the first metal to attain widespread use since the prehistoric discovery of iron.
Charles Martin Hall (born Dec. 6, 1863, Thompson, Ohio, U.S.—died Dec. 27, 1914, Daytona Beach, Fla.) was an American chemist who discovered the electrolytic method of producing aluminum, thus bringing the metal into wide commercial use.
Jan 27, 2019 · By 1914, Charles Martin Hall had brought the cost of aluminum down to 18 cents a pound, and it was no longer considered a precious metal. His discovery made him a wealthy man. Hall obtained several more patents to improve the production of aluminum.
On February 23, 1886, in his woodshed laboratory at the family home on East College Street, Charles Martin Hall succeeded in producing aluminum metal by passing an electric current through a solution of aluminum oxide in molten cryolite.
Charles Martin Hall discovered the electrolytic method of producing aluminum cheaply, bringing the metal into wide commercial use. As a young chemist experimenting in a woodshed, Charles Hall invented a method for extracting pure aluminum from its ore.
Aug 24, 2023 · Charles Martin Hall (1863–12–06 ~ 1914–12–27) was an American chemist. He was born in Thompson, Ohio. He and French metallurgist Paul-Louis-Toussaint Héroult independently discovered the cryolite-alumina electrolytic aluminum process.
Charles Martin Hall. (1863—1914) Quick Reference. (1863–1914) American chemist. Hall was born in Thompson, Ohio, and educated at Oberlin College, graduating in 1885. He became interested in the costly process of manufacturing aluminum – until the late 19th century aluminum was a precious metal costing about $5.50 an ounce.
Hall tried various added compounds and, in 1886, found that adding 10–15% of cryolite (sodium aluminum fluoride) reduced the melting point to a little over 1000°C. Hall produced his first sample in the form of buttons, which soon became known as the ‘aluminum crown jewels’.
That very year, Charles Martin Hall began his legendary experiments to produce aluminum. Under the guidance of Professor Frank Jewett, Hall worked on his experiments in an old woodshed and, in 1885, obtained his first globules of the shiny metal.
Eight months after graduating from Oberlin College in 1885 with a bachelor's degree in chemistry, Charles Martin Hall (1863-1914) invented an inexpensive method for the production of aluminum. Aluminum is light and malleable but durable.
