Abstract: PURPOSE: To provide a process where a simple and energy-saving processing is carried out later.  
     CONSTITUTION: A process for producing a bismuth-, copper-, strontium- and calcium-containing high-temperature superconductor, in which an aqueous solution is produced which has a pH of 0.5-4 and which contains the metals in an atomic ratio corresponding to a high-temperature superconductor, the solution is combined with an oxalic acid solution to precipitate the metals quantitatively as oxalates, the oxalates formed are separated off and decomposed thermally to form the oxides and the latter are allowed to react in the presence of oxygen at ≥700°C to form the desired high-temperature superconductor. The process comprises concentrating the aqueous solution of the metal until a precipitate begins to appear and using the oxalic acid as a solution in an organic solvent which is miscible with water. The oxalates are decomposed at 550-570°C in the presence of hydrogen.
