摘要：
In the process for producing molded bodies from precursors of oxidic high-temperature superconductors of the BSCCO type, a copper mold of the desired shape which encloses a solidified bismuth strontium calcium cuprate melt is wired as anode in a direct current circuit composed of anode, cathode and an electrolyte, a dilute sulfuric acid is used as electrolyte and the electrolyte is subjected to a direct current of 1 to 50 mA.cm.sup.-2 until the copper mold wired as anode is dissolved and the BSCCO molded body is laid bare.
