A two-step spray/press process for the fabrication of Hg-1223 tape on a flexible Ni-substrate coated with Cr/(Ag,Pd) has been developed by using the mechanically aligned c-axis oriented Hg-1212 micrograins as the nucleation sites for the large c-axis oriented Hg-1223 grain growth. The self-field Jc of Hg-1223 tapes so reproducibly obtained is 7×104 A/cm2 at 77 K.
