The Influence of Y211 Milling Conditions on the Microstructure of Y123/Y211 Bulk Superconductors

Abstract:

The YBCO bulk single-grain superconductors were prepared by Top-Seeded Melt-Growth (TSMG) process. Y₂BaCuO₅ (Y211) fine powder was added to YBa₂Cu₃O_7-δ (Y123) nominal composition. Powder refinement was characterized by X-ray powder difractometry, laser granulometry and scanning electron microscopy. The system behaviour was characterized by thermal analysis. Microstructure of prepared samples was studied by polarized light microscopy. The influence of Y211 addition the sample microstructures are shown.
