Abstract

It was found that with increase of NiO content the strength of non-reduced (NiO-ScCeSZ) and reduced (Ni-ScCeSZ) anodes decreased. The Ni reduction has significant influence on strength of anodes with 65 and 75% (wt.) NiO, which decreased up to 15-20% of initial value. The strength of anode is determined by contacts of sintered zirconium particles. Anodes with 40% (wt.) NiO had the best catalytic activity in temperature range 500-700оC among studied anodes.
