The History Of Aluminum And Charles Martin Hall

The History Of Aluminum And Charles Martin Hall

Jan 28 2019 aluminum is the most abundant metal element in the earths crust but it is always found in a compound rather than an easilyrefined ore alum is one such compound scientists tried to tease the metal out of alum but the process was costly until charles martin hall patented an inexpensive method to produce aluminum in 1889
