In this study, we have prepared a series of Bi2223 samples with different sintering temperatures. The XRD results show that by increasing the sintering temperature up to 865° c , the Bi2212 phase fraction decreases. It was found that the Bi2212 phase on the grain boundaries is likely to play the role of the weak links and consequently reduces the intergranular critical current densities.
