Abstract

An effect of water vapor on the micros tructure and superconducting property of high-T_c superconductors YBa₂Cu₃O_x and Bi_1.85Pb_0.35Sr_1.90Ca_2.05Cu_3.05O_y is investigated by sintering them in H₂OO₂ instead of O₂. The crystal growth, especially that at the grain boundaries, is greatly promoted by the water vapor processing. As a result, the transport critical current density J_c is remarkably enhanced.
