Abstract

PURPOSE:To produce the title dense superconducting material having high critical current by fusing or vaporizing a material contg. metal and cooling quickly while molding the material, then heating in O2-contg. atmosphere. CONSTITUTION:A material 4 contg. metallic elements such as La, Ba, Cu, etc., in, specified proportions is inserted into a quartz tube 3. After fusing the material by heating in an electric furnace 5, the fused product is extruded into aq. soln. 2 poured to a drum 1 through a nozzle 6, and molded by cooling quickly at 10<3>-10<7> deg.C/sec cooling rate, or the material 15 is mounted in a sputtering device, and sputtered in inert gas atmosphere by conducting electric current through magnets 11, 11' and a heater 12 to cause deposition on a substrate 16, and cooled quickly at 10<3>-10<7> deg.C/sec cooling rate, obtg. thus a molded body. Then, the molded body is heated at 200-1000 deg. for 3-60 min in O2-contg. atmosphere, to obtain thus a metal oxide superconducting material having a layered perovskite phase.
