Pengaruh Suhu Sintering Terhadap Pembentukan Fase Superkonduktor BSCCO-2223 dengan Kadar Ca = 2,10 Menggunakan Metode Pencampuran Basah

Abstract

This study was conducted to determine the effect of sintering temperature on the formation of BSCCO-2223 superconductor phase with levels of Ca = 2,10 using the wet mixing method. The materials used were Bi2O3, SrCO3, CaCO3, CuO, HNO3 and aquades. Synthesis is carried out by dissolving the materials using HNO3 and aquades slowly then the solution is dried for 40 hours at a temperature of 300, 400 and 600 °C gradually. The samples were calcined at 800 ° C for 10 hours and each was sintered with temperature variations of 850, 855, 860 and 865 °C for 20 hours. The XRD result shows that the sintering temperature has an effect on the formation of BSCCO-2223 superconductor phase, with volume fraction value which tends to increase with increasing sintering temperature. The highest volume fraction was obtained in the BSCCO-2223 sample with sintering temperature of 865 °C which is 79,49%. SEM result shows that all samples have arranged layers (oriented) with relatively small empty space between the plaques (void). The highest orientation degree is in the BSCCO-2223 sample with sintering temperature of 860 °C which is 23,77%.
