<![CDATA[Research about the effect of sintering time on the phase purity level of superconductor BSCCO-2223 at the level of Ca 2,10 has been synthesized using the wet-mixing method. Sample dissolved is slowly with HNO3 and aquades, then drying gradually temperature of 300, 400, 600 °C. The sample was calcined for 10 hours at 800 °C and sintered using variations of time 10, 20, 30, and 40 hours at 865°C. Variations were carried out to determine the effect of sintering time on the purification of the superconductor. XRD results show that sintering time has an effect on the volume fraction value of BSCCO-2223. Volume fraction that is relatively high at 30 hours sintering time is 79,17 % with an orientation degree value of 37.94%. While the lowest was obtained at the time of sintering for 10 hours with the volume fraction of 38.47% with a degree of orientation of 15.27%. the SEM results show that all samples have layers oriented and have relatively little space between the plates (voids). ]]>
