Goal was to develop long-lasting, energy-efficient anodes for Hall-Heroult cells used to produce Al metal. The anodes were made from a ceramic/metal composite consisting of NiO and NiFe{sub 2}O{sub 4} and a Cu/Ni metal phase. Thirteen cermet anodes were tested at Reynolds Metals Co., Muscle Shoals, AL. All anodes corroded severely during the pilot test. Electrolyte components were found deep within the anodes. However, there were many deficiencies in the pilot cell test, mainly the failure to maintain optimal operating conditions. It is concluded that there is a variety of fabrication and operational considerations that need to be addressed carefully in any future testing. 118 figs, 16 tabs, 17 refs.(DLC)
