Hans Christian Oersted, a Danish chemist, was the first to produce tiny amounts of aluminum in 1825, German chemist Friedrich WÃ¶hler developed a method that produced enough to study the metal's basic properties in 1845.
Aluminium (I) Oxide is formed by heating Al and Al2O3 in vacuo while in the presence of SiO2 and C, and only by condensing the products. Information is not commonly available on this compound due to instability, complex high-temperature spectra, difficult detection, and identification.
