High J/sub c/ YBCO superconductors prepared by the 'powder melting process'

摘要

A novel method called the powder melting process (PMP) has been developed to prepare high-J/sub c/ YBCO superconductors. The YBCO conductors have been fabricated through continuous zone melting and a unidirectional solidification process using precursor powders of Y/sub 2/BaCuO/sub 5/
