The addition of SnO2 to a mixture of TI203 and Ba2Ca3Cu307 was found to enhance the critical current density (Jc) of the subsequently fabricated superconductor. Without SnO2, the Jc of the silver-sheathed superconductor of optimal thallium content was 7.4 to 7.6 × 103 A/cm 2 at 77 K and zero externa
