Ceria sintered body doped with rare earth element and manufacturing method thereof

摘要

PPROBLEM TO BE SOLVED: To provide a doped ceria-based sintered body being dense, having a uniform structure in a nano level and having high electroconductive characteristics and to provide its producing method. PSOLUTION: The rare earth element-doped nano ceria-based sintered body is characterized by having a relative density of 95% or more, an average particle diameter of 110SP2/SPnm or more and 210SP2/SPnm or less and a standard deviation () expressing the spread of a particle diameter distribution of 610 nm or less.
