Stability of Yttrium Barium Cuprate in Molten Salts
Low critical current density is an important factor limiting utilization of YBa2Cu307−x in bulk conductor and power storage applications. The two factors that reduce critical current are the insulating nature of the grain boundaries and the anisotropic current conduction which favors the a−b plane rather than the c-direction in the orthorhombic crystal structure1,2. Fabrication of highly oriented polycrystalline bodies that approach single crystal properties would substantially alleviate the later concern. Conventional ceramic processing usually produces randomly oriented grains so special procedures are required to fabricate “grain oriented” ceramics.
