ABSTRACT:
An yttrium-barium-copper oxide powder consisting of a powdery mixture of Y.sub.2 BaCuO.sub.5 with Ba.sub.3 Cu.sub.5 O.sub.8, which can be formed into a dense sintered body having excellent superconducting characteristics. An yttrium-barium-copper oxide superconducting body is manufactured by firing the above powder preferably at 820.degree.-980.degree. C. under oxidizing atmosphere having an oxygen partial pressure of 0.01-0.5 atm.
