Sintering CeO 2 to maximum density at low temperatures retaining nanometer‐sized grains can be achieved by the addition of transition metal oxides. The densification rate and obtainable density are highly increased due to the size‐dependent melting of the dopant. The transient nature of the grain boundary layer allows tailoring of the electrical properties of CeO 2 , making this material very attractive for many electrochemical applications.
