Abstract
Sintered bars of Y-Ba-Cu oxide were partially melted using a quartz halogen lamp zone heating apparatus. The resulting multiphase samples showed varying degrees of melt texturing. It was found that the addition of YBa2CuO5 powders to the sintered YBa 2Cu3O7 prior to the zone melting process enhanced the growth of large textured grains. The best value of the critical current density was ~103 A/cm2 at 1.0 T and 77 K for the starting composition of YBa2Cu3O7-(0.2)Y2BaCuO5
