The Influence of BaCeO3 Addition on Y-211 Particle Size of YBCO Bulk Superconductors
2013
Physics Procedia
The influence of BaCeO 3 addition (1.79 wt%) on a Y 2 BaCuO 5 (Y-211) particle size and particle distribution in melt-processed YBa 2 Cu 3 O 7 / Y 2 BaCuO 5 (Y-123/Y-211) bulk superconductors was investigated. The BaCeO 3 powder was prepared by conventional solid state synthesis from BaO 2 and CeO 2 . For the particle refinement, prepared BaCeO 3 powder was milled in a planetary mill in ethanol and obtained particle size was characterized by grading analysis and SEM. The mixtures of Y-123, Y 2
