We measured the fracture strength and fracture toughness of ZrOa-based ceramics containing 14.5mo1%, 15.5mo1%, and 16.5mo1% CeO/at 298,77,and 4.2K.The results indicate that there is 56-117% increase in fracture toughness at 4.2K and 47.6-92% increase in fracture strength at 4.2K. The maximum increas
