Abstract

PURPOSE:To produce an oxide superconductor consisting of a uniform and single phase by hydrolyzing a soln. of raw materials comprising metal alkoxides of Cu, Ba, Y or a rare earth element in a solvent, and heating sprayed and transported oxide powder obtd. by evaporating the solvent. CONSTITUTION:Raw materials comprising metal alkoxides of Cu, Ba, Y or at least one kind of rare earth element are dissolved in a solvent and hydrolyzed. The solvent is then evaporated at near the b.p. to form oxide powder, and the powder is transported to an ejection nozzle 1 with gaseous Ar. Ar plasma flame of atmospheric pressure is formed previously with a work coil 3 below the ejection nozzle 1 by introducing gaseous Ar through a Pt pipe 2. The atmosphere is adjusted by mixing oxygen with the Ar plasma flame. Oxide powder passed through the Ar plasma flame deposits as sintered body 5A of the oxide on a substrate 4A heated at about 600 deg.C with a heater 6A. By this method, a uniform and single phase oxide superconductor is obtd.
