Abstract

Research about the effect of sintering time on the phase purity level of superconductor BPSCCO-2223 at the level of Ca 2,10 has been synthesized using the wet-mixing method. Synthesis carried out by slowly dissolving HNO3 and aquades then gradually for 40 hours dried out at a 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 result shows a decrease in phase purity with increasing the sintering time. Volume fraction that is relatively high at BPSCCO-2223/ts10 is 88,88%. While the lowest volume fraction of BPSCCO-2223/ts40 is 71,51%. The relative high orientation degree of BPSCCO-2223/ts30 is 33,76% and the lowest orientation degree of BPSCCO-2223/ts20 is 22,21%. The SEM result shows that all samples have layers arranged (oriented) by empty spaces between the plate (void) is relatively small.
