Title: Structural and Thermal Validations of Y{sub 3}Ba{sub 5}Cu{sub 8}O{sub 18} Composites Synthesized via Citrate Sol-Gel Spontaneous Combustion Method

Abstract

The fabrication of single-phase superconductors enabled promising advancements in a wide range of technological applications. Numerous parameters including processing temperature, thermal cycle, chemical composition, doping, and atmosphere will be carefully addressed and optimized. This paper investigates phase stability and compound formation of Y{sub 3}Ba{sub 5}Cu{sub 8}O{sub y} (Y-358) preform powders which were sintered at different temperatures. The precursor powder synthesized via chemical route and employing spontaneous combustion technique, respectively. The presence of Y-358 and YBa{sub 2}Cu{sub 3}O{sub 7-δ} (Y-123) phases in composites sintered at different temperatures with varied phase fractions were further confirmed through Rietveld refinement. The formation of Y-123 phase is dominant in all samples and composite was sintered at 900 °C, which was exhibited higher as compared to Y-358 phase content. The decomposition of different phases present in the composites and reaction temperatures were investigated with simultaneous differential thermal and thermogravimetry analysis.
