ISE - process for the production of high-purity aluminum
Process for the production of high-purity aluminum alcoholates SUBSTANCE: The process includes the pretreatment of aluminum compacts, followed by their dissolution in lower alcohols and the purification of the aluminum alcoholates obtained. The pretreatment is carried out by heat treatment until stable emissions are formed in the metal matrix which are incoherent with the primary solid solution. The invention relates to the production of organoaluminum compounds [...]

ISE - production of aluminum
Process for the electrolytic production of pure aluminum SUBSTANCE: The process involves the use of anodes containing two-phase metallic copper-based and iron-based alloys, which also contain small amounts of nickel, consisting of an iron-rich reactive phase and a copper-rich solid inert phase, which are 30 to 77 Wt .-% copper, 23 to 65 wt .-% iron and 15 wt .-% nickel [...]
