Dalton Trans. 2014 Mar 21;43(11):4305-12. doi: 10.1039/c3dt52167b.10% Praseodymium doped ceria exhibits a combination of mixed ionic and electronic conductivity, redox catalytic properties and chemical compatibility with water and carbon dioxide at high temperatures. Minor additions of cobalt oxide have been demonstrated to act as a sintering aid as well as an effective promoter of the electronic conduction. However, an excess of sintering temperature causes cobalt aggregation into the grain boundaries as inferred from FE-SEM/EDX and TEM analysis. Read More
