摘要
Fabrication of YBCO superconducting thick films by electrophoresis has been widely reported. However, the value of critical current density (Jc) is far from what the practical application requires. The superconducting thick films are obtained using top-seeded melt growth method with different proportional Y2BaCuO5 (Y211) addition. High-pressure oxygen has been used in the annealing process to improve the uniformity of the oxygen content in the superconducting thick films. When 40mol% Y211 powder is added to the YBa2Cu3O7-delta (Y123) powder, J(c) for the superconducting thick film by approaches described above reaches 7.008x10(3) A/cm(2) (77 K, 0 T), which is greater than the value ever reported.
