Niobium-doped perovskites

Han, Y., Yi, J., and Guo, X. (2014) Improving the chemical stability of oxygen permeable SrFe03 8 perovskite in CO2 by niobium doping. Solid State Ionics, 267,44-48. 

Good results are obtained with oxide-coated valve metals as anode materials. These electrically conducting ceramic coatings of p-conducting spinel-ferrite (e.g., cobalt, nickel and lithium ferrites) have very low consumption rates. Lithium ferrite has proved particularly effective because it possesses excellent adhesion on titanium and niobium [26]. In addition, doping the perovskite structure with monovalent lithium ions provides good electrical conductivity for anodic reactions. Anodes produced in this way are distributed under the trade name Lida [27]. The consumption rate in seawater is given as 10 g A ar and in fresh water is...
