The purpose of the invention is a process for making a solid part designed
to form all or part of an anode for the production of aluminium by fused
bath electrolysis, containing a cermet formed from at least one metallic
oxide such as a mixed oxide with spinel structure, and at least one
metallic phase, in which a mixed oxide is used containing a metal R in
the form of a cation in its chemical structure, the said metal R being
fully or partly reducible by a reduction operation during the
manufacturing process, so as to form all or part of the said metallic
phase. This process can provide a cermet with a uniform distribution of
fine metallic particles.
