This paper discussed strength reliability of gadolinia-doped ceria ceramics. By using strength data and fracture origin identification in the previous paper, the authors estimated shape and scale parameters in Weibull distribution on an assumption that all defects except for pores were removed from the GDC ceramics by improving its processing. It was revealed that strength reliability of GDC ceramics was remarkably increased when impurities as fracture origins were eliminated from the GDC ceramics.
