Abstract

Strength-limiting flaws were identified in gadolinium-doped ceria (GDC) ceramics in order to improve their reliability for use as a solid oxide fuel cell. GDC ceramics were prepared by dry pressing and sintering at various temperatures. The modulus of rupture was determined by 4-point bending tests and the Weibull distributions were plotted. The fracture origins were identified to determine the cause of fracture at each sintering condition.
