Abstract (en)
[origin: WO2005035813A2] The invention relates to a method for producing a solid part for forming an entire anode or the part thereof for producing aluminium by igneous electrolyse and comprising a cermet made of at least one type of metal oxide such as a spinel mixed oxide containing a R metal in the form of cations in the chemical structure thereof. Said R metal is entirely or partly reducible by a reducing operation during a production process in such a way that the entire metallic phase or the part thereof is formed. The inventive method makes it possible to obtain a cermet whose metallic phase comprises a homogenous distribution of fine metallic particles.
