摘要

A simple spray/compress technique has been developed for the fabrication of thick film tapes of HBCCO, BSCCO, and YBCO on metallic substrates with high JC. The technique has successfully incorporated crucial processing factors to achieve composition uniformity, phase purity, preferred microstructure, grain alignment, and high density for high temperature superconducting tapes of high performance. We have obtained a JC of 8.8×104 A/cm2 in YBa2Cu3O6+δ thick films on Ag/Pd substrates at 77K and self-field; 7×104 A/cm2 in HgBa2Ca2Cu3O8+δ thick films on Ni substrates with a buffer layer at 77K and self-field; and 5×105 A/cm2 and 3×105 A/cm2 in Bi2Sr2CaCu2Ox thick films on Ni substrates with a buffer layer at 4.2K in self-field and 8T, respectively.
