Thermal Decomposition Of Y123 Powder And Tsmg Y123 Bulk
Di: Zoey
The refinement and uniformity of Y2BaCuO5 (Y211) are of vital importance in preparing large-sized YBa2Cu3O7−δ (Y123) bulks with high field trapping ability by top-seeded
(Y123) powders for the fabrication of bulk superconductors were synthesized by the powder reaction method using (99.9% purity), (99.75%) and CuO (99.9%) powders. The single-grain YBCO samples were prepared by TSMG process. Two nominal compositions: 1 mol.Y123 + 0.25 mol.Y2O3 + 1.0 wt.% CeO2 (Y123/Y2O3) or 70 wt.% Y-123 + Diko, Pavel, Zmorayová, Katarína, Motoki, Takanori, Shimoyama, Jun-ichi (2023) Microstructure of DyBCO bulk superconductors prepared using single-direction melt-growth
Widespread use of YBa2Cu3O7-δ (Y123) bulk superconductors as source of strong magnetic fields requires development of high-performance materials sufficiently reliable
