Abstract Two kinds of Au powder having different particle size were mixed with a Bi−Pb−Sr−Ca−Cu−O superconductor, purpose being to improve the superconducting characteristics, especiallyJ c. By conventional Au powder addition,J c appreciably increased and a maximumJ c of 900 A/cm2 was obtained on the Au 30 wt% mixed composite. On the contrary,J c decreased by mixing with ultra fine Au powder. ThisJ c deterioration was predominantly ascribed to the formation of microcracks and poses by the segregation of Au ultra fine powder.
