So researching aluminum electrolysis inert anode material that have high anti-oxidation, corrosion resistance, high electric conductivity, high intensity and good thermal shock capability is always a dream in the aluminum electrolysis industry and materials science field, and it has important application value[2-5].
In this paper the author carried on a attempt to research, inert anode materials for aluminum electrolysis are prepared, using alumina-metal composite materials, properly increasing the content of metal , and having good dispersion with the ceramic.
Electrolyte raw materials are industrial products which are dried 2 hour at 400℃.
