Pengaruh Variasi Kadar CaCO3 terhadap Pertumbuhan Fase Superkonduktor BPSCCO–2212 Menggunakan Metode Pencampuran Basah

This research was conducted to determine the effect of CaCO3 levels on formation superconducting phase BPSCCO - 2212 by calculating level purity phases formed and looking at microstructure. The variation 0.95, 1.00, 1.05 1.10 mole using wet mixing method. samples were calcined 800 ° C for 10 hours, sintered 820 20 hours. Synthesized characterized X-Ray Diffraction (XRD) Scanning Electron Microscopy (SEM). XRD’s chacterization results show that increases with increasing Ca maximum point BPSCCO-2212/1.10 mole. highest volume fraction 79,06% in sample. While lowest 72.10% BPSCCO-2212/0.95 Meanwhile, degree orientation 20.59% BPSCCO-2212/0.95. 8.46% BPSCCO-2212/1.10. SEM’s all have been oriented altought not perfect yet relatively little space between slabs (voids).
