Azhan, F. Fariesha, S. Khalida] The effects of heat treatments and the role of Zr have been studied using X-ray diffraction (XRD) method and resistance measurement technique equipment for the structural identification and determination of critical temperature, T C. Generally, all samples displayed a normal metallic behavior above T Conset. The values of T C(R=0) have been found to decrease as Zr concentration increases. Heat treatments at 830 and 860 °C; however, have increased the critical temperature, T C in samples x=0.15 and x=0.20. The volume of the 2223-phase ratio on 2212-phase has decreased gradually toward Zr concentration. However, for samples x=0.15 and x=0.20, the ratio of 2223-phase was improved after applying heat treatment processes. The crystallographic structure remains in a tetragonal form where a=b≠c. Afew Zr is still existed in sample x=0.15 and x=0.20 although after sintering and heat treated at 830 °C implies that the excess Zr cannot incorporate into the crystalline structure of BSCCO system. After the heat treatment process at 860 °C, all these Zr peaks suddenly disappeared, and hence improved the volume of 2223-phase.
