Abstract

PURPOSE:To obtain an oxide superconducting material having scarce dispersion of superconducting characteristic and having high reliability by melting an oxide superconducting material in O2-contg. atmosphere, solidifying the material by cooling quickly to below a specified temp., and then heat-treating in O2-contg. atmosphere. CONSTITUTION:For example, each oxide of Y2O3, BaO, and Cu2O is weighed in specified mole fractions, and a crucible 2 provided with a cover 1, wherein said oxides are charged and a nozzle 5 is buried therein, is held at 1,550 deg.C by high frequency heating to melt the weighed oxides. O2 is then fed from an O2 source 6 by opening a valve 7 to stirr and enrich molten oxides with O2 sufficiently. Molten oxides are solidified by cooling quickly immediately thereafter while pressing simultaneously with a two belts quick cooling apparatus given in the drawing. The cooling velocity in this stage corresponds to a cooling velocity for cooling to below 50 deg.C within 0.5sec. An aimed oxide superconducting material is obtd. by heat-treating obtd. vitreous product in a heat-treating furnace in O2 atmosphere at, for example, 950 deg.C.
