Abstract
A high-temperature YBa.sub.2 Cu.sub.3 O.sub.x superconducting sintered body is produced through wet grain-coating process in which starting grains are soaked in SnI.sub.4 solution, pressed after the removal of solvent and then sintered at a given temperature, and has a critical current density of at least 500 A/cm.sup.2 at 77 K.
