Description
The progress of HTS technology has been particularly impressive in the last decade. The progress of commercialization of high-temperature superconducting tapes will depend on the degree of mass production and the price.. Eastern Superconductor Science& Technology(Suzhou) Co.,Ltd (Eastern Superconductor) has developed a new MOCVD technology to prepare the REBCO film. The stability of the MOCVD equipment has been significantly improved. Based on a new technological roadmap Eastern Superconductor has developed the complete set of production line for the HTS manufacture, and has achieved efficient production of s of the REBCO HTS tapes.
Here, we could achieve of critical current (Ic) above 1000A-4mm in magnetic field 10T (B//c) at 4.2 K, 10T in heavily doped (11mol.% Zr-added) REBa2Cu3O7-δ (REBCO, RE:Gd,Y) superconducting tapes. And the critical current densities (Je) could reach above 2500A/mm2 at 4.2 K, 20T (B//c) which has been used in the superconducting magnets of fusion project. By adjusting the elemental ratios (RE:Ba:Cu) the average value of lift-factor between Ic at 77 K in self-field and Ic at 4.2K, 20 T (B//c), can be 4.84 in mass production which is tested by PPMS, and all values are within the + /− 30% corridor.
